camera viewfinder vs lcd screen made in china
The benefits of the viewfinder and LCD screen are often compared with one another. Depending on whom you ask, you might hear remarkably different opinions on the usability of the two.
As discussed above, photography is all about precision. Viewfinders have been around long before LCD screens, and therefore many photographers find viewfinders more comfortable to work with.
Viewfinders offer much more precision when you are shooting, especially on a bright day. It allows you to focus on the small details. Viewfinders reduce image distortion and capture an accurate image. That’s why most DSLRs and high-end mirrorless cameras today still have viewfinders.
Running out of battery is a nightmare for photographers, especially if you don’t have any spares. That’s why viewfinders are considered optimal in these situations. Viewfinders use comparatively much less battery than LCD screens.
If you are shooting in an area where electricity is scarce, or don’t have access to a charger or backup batteries, the viewfinder will be a better choice for you.
Viewfinders are very convenient to use and provide smooth handling. When looking through the viewfinder, it’s easy to keep the camera steady. This makes the viewfinder an optimal choice when you need to zoom in or have a slightly heavier camera.
For many people, this extra effort of adjusting your eyeglasses is troublesome. However, some viewfinder cameras have a built-in diopter that can help make it easier to use with glasses.
Viewfinders can be much smaller compared to LCD screens. As a result, you may not be able to see everything you’re capturing in the viewfinder accurately. This drawback is very important for photographers who want to preview every single detail when taking a picture.
To see details on viewfinders, especially the electronic ones, you have to zoom in on the frame. However, this can lower the resolution of the preview. Luckily, if most of your shots consist of zoom shots, this may not bother you much.
What sets LCD screens apart from viewfinders is their ability to provide 100% image coverage to the photographer. In comparison, cameras with a viewfinder offer around 90-95% of the image, sometimes less.
What you see through the viewfinder doesn’t always end up in the final result. Small details can be crucial. That’s why this 5-10% difference in image coverage can be a significant reason why you might choose an LCD screen over the viewfinder.
When you are in a lower field-of-view, framing can be much more difficult. Many people can’t take a picture while lying on the ground using a viewfinder. This is where LCD screens come in. Flexible LCDs make it easier for you to capture images when you can’t reach awkward angles.
LCD screens produce great results for night photography. LCD screens are often used for night photography due to their bright image playback quality. They help you focus on the small details when you are shooting at night.
An evident shortcoming of the LCD screen is its lack of utility on a bright day. Because of the glare, many people cannot use their LCD screen at all on a sunny day. It’s hard to see anything on the LCD except the reflections.
Another drawback to using an LCD screen is its difficulty in handling it. Holding the camera while looking through the LCD screen is difficult and takes a lot of effort, especially when you are zooming and trying to be precise.
Another disadvantage of LCD screens is the fact that they can easily overexpose your image. This should not be a problem for seasoned photographers who can improve the quality of the image with better handling and precision.
Those were some of the benefits and drawbacks of using a viewfinder and LCD screen to consider. So, which one is best? The answer depends on your personal preferences and budget.
If you’re a traditional photographer, you’ll probably be more comfortable with the viewfinder. If you are a photographer who likes to focus on small details and image quality, you should opt for the LCD screen.
LCD screens are great, and the quality improves with each new generation of DSLR cameras appearing on the market. But, many professional photographers prefer to use a camera"s viewfinder. We explain the benefits and disadvantages of each.
LCD screens have advantages, but so do optical viewfinders. When it"s time to frame a photo with your DSLR camera, you need to decide which side of the viewfinder vs. LCD debate you lean. Unlike the optical viewfinder, the LCD screen displays the entire frame that the sensors capture. Optical viewfinders, even on a professional level DSLR, only show 90-95% of the image. You lose a small percentage on the edges of the image.
Digital SLRs aren"t light, and it"s easier to produce a crisp, sharp image when you hold the camera up to your eye to use the viewfinder. That way, you can support and steady the camera and lens with your hands. But, viewfinders are generally smaller than LCD screens. Viewfinders are also less convenient to use, especially if you wear glasses.
At the end of the day, though, as intelligent as digital cameras are, the human eye can resolve more detail than an LCD screen. You get a sharper and more accurate view of your image by using the viewfinder.
The biggest drawback with LCD screens is probably shooting in sunlight. Depending on the quality of the screen, you may not be able to use it in bright sunshine because of the glare. All you see are reflections off the screen. Also, the crystals contained within LCD screens tend to flare in bright sunlight, making the situation worse.
Holding the camera at arm"s-length while looking at the LCD screen—and then keeping the camera steady while zooming in on a subject—takes effort. When you use the LCD screen this way, you often end up with a blurry image.
No matter how good an LCD screen is, it"s unlikely to give an accurate overview of the image you took. Most overexpose an image by as much as one full stop. It"s best to acquire the technical knowledge about photography, rather than rely on the LCD screen to determine image quality. With this technical knowledge, you"ll have the confidence your settings are correct, and your images are properly exposed. So, in most cases, it"s best to use the viewfinder. But, if you like the convenience of an LCD, or you wear glasses, use the LCD. It"s mostly a matter of personal preference.
Shooting with the rear LCD screen on your camera may be convenient, but you"re also peering through a filter of colors and shades that you may not have been aware are altering the way you perceive your shots.
There are several reasons why you might want to take photographs using the rear LCD screen on your digital camera. It could be to overlay information such as a spirit level, camera settings, or to utilize the rule of thirds grid in order to achieve better composition. Perhaps you wear glasses or have an issue with vision in which using the viewfinder may detrimentally impact your ability to compose or shoot. It might even be that you"re shooting with your camera at awkward angles, maybe holding the camera down low to the ground to capture a macro shot of a flower or perhaps overhead at a crowded concert, where a tilting or vari-angle screen can be articulated to help with composition.
Camera brands use different LCD screens, so you and a friend could be taking a picture of the same scene and end up with wildly different-looking results when doing an image review together. Even models within specific manufacturers use different screens, so the reliability and uniformity of each screen for things such as color can be over-emphasized.
With the advent of mirrorless cameras and the introduction of the electronic viewfinder (EVF), we now have digital cameras where we literally can"t avoid shooting and reviewing photographs through a screen. The benefits of using an EVF over the rear screen is that the screen is sheltered from reflections and extraneous light, which can affect the perception of photos when using the rear screen. However, these tiny little screens inside a small box in the camera still don"t produce an ideal picture of your photographs.
Whatever the reason, it"s important not to rely on the scene on your rear screen. An assumption that what you see is what you"ve taken is tempting but a little foolish. That"s because the screen has a limit to the light and shade it can display. It also has a color balance, which can affect the white balance or color profile you attribute to shots. This unintentional filtration can have a negative effect on how you capture images. Some cameras have the option to turn the brightness of their screen up and down, which also affects how images on the rear screen are seen (whether using live view or to display photos already taken) as well as altering color balance of the rear screen manually. One way to mitigate this is to turn on the histogram and use that.
Notwithstanding these options and difficulties in the limitation of the screen technology, where you view your photos also has a big impact on what you see. Looking at a screen at night, for example, you might need to turn the brightness down to avoid blinding yourself. The vivid lower frequency colors of sunset or sunrise light may be cascading warm tones across and around the screen, forcing you to perceive the color temperature in the photograph differently. If you don"t believe me, have a look at color theory illusions online, and you"ll see just how easy it is for the eye to be tricked into perceiving things as the same, even though they"re different, or seeing the same colors or shades in a scene when in fact they"re completely different (remember the dress from 2015?).
That"s why I suggest you can maintain a healthy balance between relying on your rear screen for certain aspects of shooting such as composition, leveling, framing a scene, and getting a rough visual idea of how the photograph is coming together. But I would advise against relying on the screen to discern color, brightness of highlights and shadows, and other such optical aspects. For this, I would recommend the use of the histogram in camera, especially when needing to check if highlights or shadows have been over/underexposed and have become clipped. Your camera may also have a dedicated function to alert you to this. This and combining the approach with color swatches and gray cards can be a very good way to attain accurate color and exposure values in photographs.
It"s good practice to take stills in raw format, where the color and exposure is much more flexibly editing in post-production image editing software and study images on a decent monitor screen that can display a wide color gamut with deep shadows and bright highlights to get the most accurate view of what your photographs actually look like.
Try to view them in a low-light room with minimal reflections. You might want to consider using a screen hood to remove unwanted reflections further from obscuring your view (think of viewing shots on the rear screen outside during the midday sun and how difficult it is to see what"s going on without putting your hand round to screen to shade it from the bright light). So, although the rear screen is incredibly useful, it"s important not to rely on the rear screen for color rendition and exposure accuracy and instead look for more reliable methods for balancing your digital photos.
If you"ve had a shoot ruined by the color or brightness bias of your rear screen or perhaps think that the rear screen is the better way to compose shots over the optical viewfinder or relying on a good photographic computer monitor, then I"d love to hear your thoughts in the comments below.
While some photographers like the natural view offered by an optical viewfinder, an electronic viewfinder brings the advantage of being able to see the effect of the exposure, white balance and Picture Style settings being applied. If you apply the Monochrome Picture Style, for example, the image you see in the EVF will be mono, while with an OVF it will remain colour. This means you can use the image in an EVF to assess whether your settings suit the scene and to be confident you will get the result you want before pressing the shutter button. That"s especially helpful if, for example, the subject is backlit and you might need to use some exposure compensation.
In this way, an EVF is especially useful for relatively inexperienced photographers, because it enables you to see the effects of camera settings at the shooting stage, not just assess them afterwards. For many, it makes photography more intuitive.
Another advantage of an EVF is that it can compensate for low light levels, which means you always have a clear view of the subject. Conversely, with an optical viewfinder you"re seeing the scene with the ambient light level, which means that in dark conditions it can be difficult to compose a shot or to focus.
On the other hand, because the image you see in an EVF has to be processed before it can be displayed, all EVFs suffer from some degree of lag. Although the latest mirrorless cameras such as the EOS R5 have EVFs with a refresh rate of 120fps and the lag is only a matter of milliseconds, this can still matter if you"re shooting fast-moving action and split-second timing is critical. As technologies continue to develop, the lag is likely to get shorter and shorter, but an OVF works at the speed of light, which means in effect no lag at all. For this reason, many photographers shooting sports, wildlife or other subjects involving fast action still prefer a DSLR.
In addition, when you"re using an EVF you"re actually looking at a small screen, and even though this has a very high refresh rate, an OVF can be more comfortable over a long period of usage. This means that if you"re shooting wildlife or sports where you have to keep your eye to the viewfinder for a very long time waiting for the action to happen, an OVF could be preferable.
Depending on the image, there could be noticeable differences when viewing via viewfinder versus the LCD screen - the camera has default settings and image taken in natural daylight. The viewfinder is reasonably accurate as close to the image displayed on a computer. However the same image on LCD can be "off" in terms of whites having a slight tinge of yellow hue and also other slight shading differences.
Has anyone else noticed this as rather frustrating to have the differences. Also this means having to double check with the more accurate viewfinder to avoid unnecessary corrections.
You know how people have been raving about the 2.4-million dot viewfinder Sony squeezed into the NEX 7 camera111? A tiny optical viewfinder that manages to pack in almost three times more dots than found in the highest-end camera viewing screens?
Well, that "finder is now officially lame, a crappy 8-bit-style pixelated mess in the face of a magnificent new screen from French company MicroOLED, which sports a staggering 5 million dots (remember, though, dots doesn"t equal pixels. For a regular RGB display, divide by three).
The MicroOLED "finder is aimed at high-end cameras and video cameras, and may also come with RGBW (RGB plus white) pixels for a 100,000:1 contrast ratio (ten times Sony"s). This new chip is clearly a "retina" display for close-up viewing, and could make the optical viewfinder obsolete.
Think about it: with such high resolution, optical viewfinders lose their one advantage. Now you can ditch extra lenses and/or mirrors, you can zoom, overlay info on the screen and still manually focus as easily as with optical. Bonus: the optical "finders in even high-end compacts like the Canon G-series suck to the point of uselessness. They will be needed no more.
The LCD screen on digital cameras cuts out the need for this process as images can be viewed immediately after they are taken and adjustments can be made to improve your shots straight away.
If you like to record your images settings for future analysis, most digital cameras will do this for you – to be viewed later either on your camera (using the ‘info’ function when in playback on many cameras) or on your computer.
One question I get asked a lot by readers is whether they should use their digital camera’s LCD screen or viewfinder to frame their shots. I suspect that the majority of camera owners do use the LCD but there are a number of arguments both for and against it. Let me explore a few:
Convenience – Perhaps the main reason that people use the LCD is convenience. Rather than having to fire up the camera, raise it to your eye, squint through it (on many point and shoot models it’s quite small) etc… using the LCD means you simply switch the camera on and from almost any position you can snap a shot.
Size – As I hinted above – many models of digital cameras have very small view finders and when compared with the LCD (usually between 1.5 and 2.5 inches these days) there is really not that much of a comparison.
Instant Playback – shooting with the LCD means that after you take your shot you will immediately see the shot you’ve taken flashed onto the screen. You can see this if you use the viewfinder too by lowering the camera but it adds another action to the process.
Creativity – using the LCD opens up all kinds of creative opportunities for your photography by meaning that you don’t have to have the camera at eye level to be able to get your framing right. You can instead put it up high or down low and still be able to line things up well.
Framing Inaccuracy of Optical Viewfinders on Point and Shoots – one of the most common complaints about using the viewfinder on digital cameras is that what you see through it is slightly different to what the camera is actually seeing as the view finder is generally positioned above and to the left of the lens which means it is slightly different (a problem called parallax). Most viewfinders that have this will give you a guide as to where to frame your shot but it can be a little difficult – especially when taking close up/macro shots. (note that not all point and shoot cameras have optical viewfinders – some have electronic ones (see below).
Obstructed View – on some models of point and shoot digital cameras a fully extended zoom can actually obstruct the view from your viewfinder. This can be quite frustrating.
Glasses Wearers – if you wear glasses you might find using the viewfinder of your Digital camera more difficult. Many these days do come with a little diopter adjuster to help with this.
Battery Killer– the LCD on your camera chews up battery power faster than almost any other feature on your camera. Use it not only for viewing shots taken but lining them up and you’ll need to recharge a lot more regularly.
Camera Shake – when shooting with the LCD as a viewfinder you need to hold your camera away from your body (often at arms length). This takes the camera away from your solid and still torso and into midair (only supported by your outstretched arms) – this increased the chance that your camera will be moving as you take the shot which will result in blurry shots.
Competing Light – one problem that you will often have with framing your shots using the LCD is that for many cameras, shooting in bright light will make it difficult to see the LCD – leaving it looking washed out. Digital camera manufacturers are trying to overcome this with brighter and clearer screens but using the viewfinder instead of the LCD will generally overcome the problem.
DSLRs – most DSLRs do not give you the opportunity to use the LCD as a viewfinder at all. I suspect that this feature will become more available however as I hear it being asked for quite a bit. I’m not sure I’d ever use it though as DSLR view finders are generally larger and are a WYSIWYG (what you see is what you get) meaning you can be sure that what you’re looking at through the view finder is what the image will be when you shoot.
Electronic View Finders (EVF)– another type of view finder that is found on some point and shoot digital cameras is the EVF one. This overcomes the problem of your viewfinder and camera seeing slightly different things by giving you an exact picture of the scene you’re photographing in the viewfinder. This happens simply by putting a little LCD in the viewfinder.
Ultimately the choice in using the LCD or viewfinder will come down to personal preference. I have used a variety of digital cameras over the past few years and find myself using both methods depending upon the shooting situation and the camera. Some cameras have large and clear viewfinders (like my DSLR) and so I use them. Others have tiny viewfinders (in fact my latest point and shoot, the Fujifilm Finepix F10, doesn’t have one at all).
Given the choice between a great viewfinder and great LCD I’d probably opt for the viewfinder – call me a traditionalist but it just feels right for me.
I had a Hoodman on an older camera and liked it, though it didn"t last long. The inner spring quit. When I upgraded my camera I checked for a new one but I couldn"t find one for my d-7100. Then I saw this one.
First impressions is that this one isn"t as durable as the hoodman. The hoodman attached to the view finder and the LCD screen. This one only attaches to the view finder. The plastic doesn"t seem strong enough so when I pop open the hood, it feels like I could break the plastic. It doesn"t have the professional feel as the hoodman. It blocks out any glare that you might get on your LCD. This one cost much less than the name brand but this has a feature the hoodman didn"t have.
The hood on this one detaches with a simple slide. This comes in handy when I"m reviewing after every shot, which I don"t usually. The only bad thing about this feature is that maybe it detaches just a little too easy. Time will tell. I may just lose the thing while my camera hangs off my shoulder.
Manipulating the buttons around the LCD screen feels a little awkward, but not undo able. I haven"t gone out shooting with it yet because of this pandemic and I think I"ve shot just about everything close to home.
A digital camera is a camera that captures photographs in digital memory. Most cameras produced today are digital,photographic film. Digital cameras are now widely incorporated into mobile devices like smartphones with the same or more capabilities and features of dedicated cameras (which are still available).
Digital and digital movie cameras share an optical system, typically using a lens with a variable diaphragm to focus light onto an image pickup device.shutter admit a controlled amount of light to the image, just as with film, but the image pickup device is electronic rather than chemical. However, unlike film cameras, digital cameras can display images on a screen immediately after being recorded, and store and delete images from memory. Many digital cameras can also record moving videos with sound. Some digital cameras can crop and stitch pictures and perform other elementary image editing.
In the 1960s, Eugene F. Lally of the Jet Propulsion Laboratory was thinking about how to use a mosaic photosensor to capture digital images. His idea was to take pictures of the planets and stars while travelling through space to give information about the astronauts" position.Texas Instruments employee Willis Adcock"s film-less camera (US patent 4,057,830) in 1972,

Nikon has been interested in digital photography since the mid-1980s. In 1986, while presenting to Photokina, Nikon introduced an operational prototype of the first SLR-type electronic camera (Still Video Camera), manufactured by Panasonic.pixels. Storage media, a magnetic floppy disk inside the camera allows recording 25 or 50 B&W images, depending on the definition.
At Photokina 1988, Fujifilm introduced the FUJIX DS-1P, the first fully digital camera, capable of saving data to a semiconductor memory card. The camera"s memory card had a capacity of 2 MB of SRAM (static random-access memory), and could hold up to ten photographs. In 1989, Fujifilm released the FUJIX DS-X, the first fully digital camera to be commercially released.Toshiba"s 40 MB flash memory card was adopted for several digital cameras.

However, it could not send the resulting image over the telephone function, but required a computer connection to access photos.J-SH04, a Sharp J-Phone model sold in Japan in November 2000.cell phones had an integrated digital camera and by the early 2010s, almost all smartphones had an integrated digital camera.
The two major types of digital image sensor are CCD and CMOS. A CCD sensor has one amplifier for all the pixels, while each pixel in a CMOS active-pixel sensor has its own amplifier.back-side-illuminated CMOS (BSI-CMOS) sensor. The image processing capabilities of the camera determine the outcome of the final image quality much more than the sensor type.
The resolution of a digital camera is often limited by the image sensor that turns light into discrete signals. The brighter the image at a given point on the sensor, the larger the value that is read for that pixel.
Depending on the physical structure of the sensor, a color filter array may be used, which requires demosaicing to recreate a full-color image. The number of pixels in the sensor determines the camera"s "pixel count".
An image sharpness is presented through the crisp detail, defined lines, and its depicted contrast. Sharpness is a factor of multiple systems throughout the DSLR camera by its ISO, resolution, lens and the lens settings, the environment of the image and its post processing. Images have a possibility of being too sharp but it can never be too in focus.
A digital camera resolution is determined by a digital sensor. The digital sensor indicates a high level of sharpness can be produced through the amount of noise and grain that is tolerated through the lens of the camera. Resolution within the field of digital still and digital movie is indicated through the camera"s ability to determine detail based on the distance which is then measured by frame size, pixel type, number, and organization although some DSLR cameras have resolutions limited it almost impossible to not have the proper sharpness for an image. The ISO choice when taking a photo effects the quality of the image as high ISO settings equates to an image that is less sharp due to increased amount of noise allowed into the image along with too little noise can also produce an image that is not sharp.
Digital camera, partially disassembled. The lens assembly (bottom right) is partially removed, but the sensor (top right) still captures an image, as seen on the LCD screen (bottom left).
Single-shot capture systems use either one sensor chip with a Bayer filter mosaic, or three separate image sensors (one each for the primary additive colors red, green, and blue) which are exposed to the same image via a beam splitter (see Three-CCD camera).
The third method is called scanning because the sensor moves across the focal plane much like the sensor of an image scanner. The linear or tri-linear sensors in scanning cameras utilize only a single line of photosensors, or three lines for the three colors. Scanning may be accomplished by moving the sensor (for example, when using color co-site sampling) or by rotating the whole camera. A digital rotating line camera offers images consisting of a total resolution that is very high.
Improvements in single-shot cameras and image file processing at the beginning of the 21st century made single shot cameras almost completely dominant, even in high-end commercial photography.
Cameras that use a beam-splitter single-shot 3CCD approach, three-filter multi-shot approach, color co-site sampling or Foveon X3 sensor do not use anti-aliasing filters, nor demosaicing.
Firmware in the camera, or a software in a raw converter program such as Adobe Camera Raw, interprets the raw data from the sensor to obtain a full color image, because the RGB color model requires three intensity values for each pixel: one each for the red, green, and blue (other color models, when used, also require three or more values per pixel).
Cameras with digital image sensors that are smaller than the typical 35 mm film size have a smaller field or angle of view when used with a lens of the same focal length. This is because angle of view is a function of both focal length and the sensor or film size used.
The crop factor is relative to the 35mm film format. If a smaller sensor is used, as in most digicams, the field of view is cropped by the sensor to smaller than the 35 mm full-frame format"s field of view. This narrowing of the field of view may be described as crop factor, a factor by which a longer focal length lens would be needed to get the same field of view on a 35 mm film camera. Full-frame digital SLRs utilize a sensor of the same size as a frame of 35 mm film.
Common values for field of view crop in DSLRs using active pixel sensors include 1.3x for some Canon (APS-H) sensors, 1.5x for Sony APS-C sensors used by Nikon, Pentax and Konica Minolta and for Fujifilm sensors, 1.6 (APS-C) for most Canon sensors, ~1.7x for Sigma"s Foveon sensors and 2x for Kodak and Panasonic 4/3-inch sensors currently used by Olympus and Panasonic. Crop factors for non-SLR consumer compact and bridge cameras are larger, frequently 4x or more.
The resolution of a digital camera is often limited by the image sensor that turns light into discrete signals. The brighter the image at a given point on the sensor, the larger the value that is read for that pixel. Depending on the physical structure of the sensor, a color filter array may be used, which requires demosaicing to recreate a full-color image. The number of pixels in the sensor determines the camera"s "pixel count". In a typical sensor, the pixel count is the product of the number of rows and the number of columns. Pixels are square and is often equal to 1, for example, a 1,000 by 1,000 pixel sensor would have 1,000,000 pixels, or 1 megapixel. On full-frame sensors (i.e., 24 mm 36 mm), some cameras propose images with 20–25 million pixels that were captured by 7.5–m photosites, or a surface that is 50 times larger.
Digital cameras come in a wide range of sizes, prices and capabilities. In addition to general purpose digital cameras, specialized cameras including multispectral imaging equipment and astrographs are used for scientific, military, medical and other special purposes.
Compact cameras are usually designed to be easy to use. Almost all include an automatic mode, or "auto mode", which automatically makes all camera settings for the user. Some also have manual controls. Compact digital cameras typically contain a small sensor which trades-off picture quality for compactness and simplicity; images can usually only be stored using lossy compression (JPEG). Most have a built-in flash usually of low power, sufficient for nearby subjects. A few high end compact digital cameras have a hotshoe for connecting to an external flash. Live preview is almost always used to frame the photo on an integrated LCD. In addition to being able to take still photographs almost all compact cameras have the ability to record video.
Compacts often have macro capability and zoom lenses, but the zoom range (up to 30x) is generally enough for candid photography but less than is available on bridge cameras (more than 60x), or the interchangeable lenses of DSLR cameras available at a much higher cost.Autofocus systems in compact digital cameras generally are based on a contrast-detection methodology using the image data from the live preview feed of the main imager. Some compact digital cameras use a hybrid autofocus system similar to what is commonly available on DSLRs.
Typically, compact digital cameras incorporate a nearly silent leaf shutter into the lens but play a simulated camera sound for skeuomorphic purposes.
For low cost and small size, these cameras typically use image sensor formats with a diagonal between 6 and 11 mm, corresponding to a crop factor between 7 and 4. This gives them weaker low-light performance, greater depth of field, generally closer focusing ability, and smaller components than cameras using larger sensors. Some cameras use a larger sensor including, at the high end, a pricey full-frame sensor compact camera, such as Sony Cyber-shot DSC-RX1, but have capability near that of a DSLR.
Starting in 2011, some compact digital cameras can take 3D still photos. These 3D compact stereo cameras can capture 3D panoramic photos with dual lens or even single lens for play back on a 3D TV.
Rugged compact cameras typically include protection against submersion, hot and cold conditions, shock and pressure. Terms used to describe such properties include waterproof, freeze-proof, heatproof, shockproof and crushproof, respectively. Nearly all major camera manufacturers have at least one product in this category. Some are waterproof to a considerable depth up to 100 feet (30 m);
GoPro and other brands offer action cameras which are rugged, small and can be easily attached to helmets, arms, bicycles, etc. Most have wide angle and fixed focus, and can take still pictures and video, typically with sound.
The 360-degree camera can take picture or video 360 degrees using two lenses back-to-back and shooting at the same time. Some of the cameras are Ricoh Theta S, Nikon Keymission 360 and Samsung Gear 360. Nico360 was launched in 2016 and claimed as the world"s smallest 360-degree camera with size 46 x 46 x 28 mm (1.8 x 1.8 x 1.1 in) and price less than $200. With virtual reality mode built-in stitching, Wifi, and Bluetooth, live streaming can be done. Due to it also being water resistant, the Nico360 can be used as action camera.
Bridge cameras physically resemble DSLRs, and are sometimes called DSLR-shape or DSLR-like. They provide some similar features but, like compacts, they use a fixed lens and a small sensor. Some compact cameras have also PSAM mode.manual focus mode and some have a separate focus ring for greater control.
Big physical size and small sensor allow superzoom and wide aperture. Bridge cameras generally include an image stabilization system to enable longer handheld exposures, sometimes better than DSLR for low light conditions.
As of 2014, bridge cameras come in two principal classes in terms of sensor size, firstly the more traditional 1/2.3" sensor (as measured by image sensor format) which gives more flexibility in lens design and allows for handholdable zoom from 20 to 24 mm (35 mm equivalent) wide angle all the way up to over 1000 mm supertele, and secondly a 1" sensor that allows better image quality particularly in low light (higher ISO) but puts greater constraints on lens design, resulting in zoom lenses that stop at 200 mm (constant aperture, e.g. Sony RX10) or 400 mm (variable aperture, e.g. Panasonic Lumix FZ1000) equivalent, corresponding to an optical zoom factor of roughly 10 to 15.
Some bridge cameras have a lens thread to attach accessories such as wide-angle or telephoto converters as well as filters such as UV or Circular Polarizing filter and lens hoods. The scene is composed by viewing the display or the electronic viewfinder (EVF). Most have a slightly longer shutter lag than a DSLR. Many of these cameras can store images in a raw format in addition to supporting JPEG.
In bright sun, the quality difference between a good compact camera and a digital SLR is minimal but bridge cameras are more portable, cost less and have a greater zoom ability. Thus a bridge camera may better suit outdoor daytime activities, except when seeking professional-quality photos.
In late 2008, a new type of camera emerged, called a DSLR camera that does not require a reflex mirror, a key component of the former. While a typical DSLR has a mirror that reflects light from the lens up to the optical viewfinder, in a mirrorless camera, there is no optical viewfinder. The image sensor is exposed to light at all times, giving the user a digital preview of the image either on the built-in rear LCD screen or an electronic viewfinder (EVF).
These are simpler and more compact than DSLRs due to not having a lens reflex system. MILCs, or mirrorless cameras for short, come with various sensor sizes depending on the brand and manufacturer, these include: a small 1/2.3 inch sensor, as is commonly used in bridge cameras such as the original Pentax Q (more recent Pentax Q versions have a slightly larger 1/1.7 inch sensor); a 1-inch sensor; a Micro Four Thirds sensor; an APS-C sensor found in Sony NEX series and α "DSLR-likes", Fujifilm X series, Pentax K-01, and Canon EOS M; and some, such as the Sony α7, use a full frame (35 mm) sensor, with the Hasselblad X1D being the first medium format mirrorless camera. Some MILCs have a separate electronic viewfinder to compensate the lack of an optical one. In other cameras, the back display is used as the primary viewfinder in the same way as in compact cameras. One disadvantage of mirrorless cameras compared to a typical DSLR is its battery life due to the energy consumption of the electronic viewfinder, but this can be mitigated by a setting inside the camera in some models.
Olympus and Panasonic released many Micro Four Thirds cameras with interchangeable lenses that are fully compatible with each other without any adapter, while others have proprietary mounts. In 2014, Kodak released its first Micro Four Third system camera.
While most digital cameras with interchangeable lenses feature a lens-mount of some kind, there are also a number of modular cameras, where the shutter and sensor are incorporated into the lens module.
The first such modular camera was the Minolta Dimâge V in 1996, followed by the Minolta Dimâge EX 1500 in 1998 and the Minolta MetaFlash 3D 1500 in 1999. In 2009, Ricoh released the Ricoh GXR modular camera.
At CES 2013, Sakar International announced the Polaroid iM1836, an 18MP camera with 1"-sensor with interchangeable sensor-lens. An adapter for Micro Four Thirds, Nikon and K-mount lenses was planned to ship with the camera.
There are also a number of add-on camera modules for smartphones, they are called lens-style cameras (lens camera or smart lens). They contain all the essential components of a digital camera inside a DSLR lens-shaped module, hence the name, but lack any sort of viewfinder and most controls of a regular camera. Instead, they are connected wirelessly and/or mounted to a smartphone to be used as its display output and operate the camera"s various controls.
Sony Cyber-shot QX series "Smart Lens" or "SmartShot" cameras, announced and released in mid 2013 with the Cyber-shot DSC-QX10. In January 2014, a firmware update was announced for the DSC-QX10 and DSC-QX100.DSC-QX30 as well as the Alpha ILCE-QX1,Sony E-mount instead of a built-in lens.
Kodak PixPro smart lens camera series, announced in 2014. These include: the 5X optical zoom SL5, 10X optical zoom SL10, and the 25X optical zoom SL25; all featuring 16MP sensors and 1080p video recording, except for the SL5 which caps at 720p.
Olympus Air A01 lens camera, announced in 2014 and released in 2015, the lens camera is an open platform with an Android operating system and can detach into 2 parts (sensor module and lens), just like the Sony QX1, and all compatible Micro Four Thirds lenses can then be attached to the built-in lens mount of the camera"s sensor module.
Digital single-lens reflex cameras (DSLR) is a camera with a digital sensor that utilizes a reflex mirror to split or direct light into the viewfinder to produce an image.
The sensor also known as a full-frame sensor is much larger than the other types, typically 18mm to 36mm on the diagonal (crop factor 2, 1.6, or 1).interchangeable lenses for versatility by removing it from the lens mount of the camera, typically a silver ring on the front side of DSLRs.
Digital Still Camera (DSC), such as the Sony DSC cameras, is a type of camera that doesn"t use a reflex mirror. DSCs are like point-and-shoot cameras and are the most common type of cameras, due to their comfortable price and its quality.
Cameras with fixed semi-transparent mirrors, also known as DSLT cameras, such as the Sony SLT cameras, are single-lens without a moving reflex mirror as in a conventional DSLR. A semi-transparent mirror transmits some of the light to the image sensor and reflects some of the light along the path to a pentaprism/pentamirror which then goes to an optical view finder (OVF) as is done with a reflex mirror in DSLR cameras. The total amount of light is not changed, just some of the light travels one path and some of it travels the other. The consequences are that DSLT cameras should shoot a half stop differently from DSLR. One advantage of using a DSLT camera is the blind moments a DSLR user experiences while the reflecting mirror is moved to send the light to the sensor instead of the viewfinder do not exist for DSLT cameras. Because there is no time at which light is not traveling along both paths, DSLT cameras get the benefit of continuous auto-focus tracking. This is especially beneficial for burst-mode shooting in low-light conditions and also for tracking when taking video.
A rangefinder is a device to measure subject distance, with the intent to adjust the focus of a camera"s objective lens accordingly (open-loop controller). The rangefinder and lens focusing mechanism may or may not be coupled. In common parlance, the term "rangefinder camera" is interpreted very narrowly to denote manual-focus cameras with a visually-read out optical rangefinder based on parallax. Most digital cameras achieve focus through analysis of the image captured by the objective lens and distance estimation, if it is provided at all, is only a byproduct of the focusing process (closed-loop controller).

A line-scan camera traditionally has a single row of pixel sensors, instead of a matrix of them. The lines are continuously fed to a computer that joins them to each other and makes an image.frame grabber which resides in a PCI slot of an industrial computer. The frame grabber acts to buffer the image and sometimes provide some processing before delivering to the computer software for processing. Industrial processes often require height and width measurements performed by digital line-scan systems.
Many industrial applications require a wide field of view. Traditionally maintaining consistent light over large 2D areas is quite difficult. With a line scan camera all that is necessary is to provide even illumination across the “line” currently being viewed by the camera. This makes sharp pictures of objects that pass the camera at high speed.
Such cameras are also commonly used to make photo finishes, to determine the winner when multiple competitors cross the finishing line at nearly the same time. They can also be used as industrial instruments for analyzing fast processes.
Line-scan cameras are also extensively used in imaging from satellites (see push broom scanner). In this case the row of sensors is perpendicular to the direction of satellite motion. Line-scan cameras are widely used in scanners. In this case, the camera moves horizontally.
This type of digital camera captures information about the light field emanating from a scene; that is, the intensity of light in a scene, and also the direction that the light rays are traveling in space. This contrasts with a conventional digital camera, which records only light intensity.
Many devices have a built-in digital camera, including, for example, smartphones, mobile phones, PDAs and laptop computers. Built-in cameras generally store the images in the JPEG file format.
Mobile phones incorporating digital cameras were introduced in Japan in 2001 by J-Phone. In 2003 camera phones outsold stand-alone digital cameras, and in 2006 they outsold film and digital stand-alone cameras. Five billion camera phones were sold in five years, and by 2007 more than half of the installed base of all mobile phones were camera phones. Sales of separate cameras peaked in 2008.
There are many manufacturers that lead in the production of digital cameras (commonly DSLRs). Each brand embodies different mission statements that differ them from each other outside of the physical technology that they produce. While the majority of manufacturers share modern features amongst their production of cameras, some specialize in specific details either physically on camera or within the system and image quality.

Sales of traditional digital cameras have declined due to the increasing use of smartphones for casual photography, which also enable easier manipulation and sharing of photos through the use of apps and web-based services. "Bridge cameras", in contrast, have held their ground with functionality that most smartphone cameras lack, such as optical zoom and other advanced features.
In response to the convenience and flexibility of smartphone cameras, some manufacturers produced "smart" digital cameras that combine features of traditional cameras with those of a smartphone. In 2012, Nikon and Samsung released the Coolpix S800c and Galaxy Camera, the first two digital cameras to run the Android operating system. Since this software platform is used in many smartphones, they can integrate with some of the same services (such as e-mail attachments, social networks and photo sharing sites) that smartphones do and use other Android-compatible software.
In an inversion, some phone makers have introduced smartphones with cameras designed to resemble traditional digital cameras. Nokia released the 808 PureView and Lumia 1020 in 2012 and 2013; the two devices respectively run the Symbian and Windows Phone operating systems, and both include a 41-megapixel camera (along with a camera grip attachment for the latter).Galaxy S4 Mini with the Galaxy Camera.Leica fixed lens equivalent of 28 mm at F2.8, can take RAW image and 4K video, has 21 mm thickness.Huawei P20 Pro is an android Oreo 8.1 has triple Leica lenses in the back of the smartphone with 40MP 1/1.7" RGB sensor as first lens, 20MP 1/2.7" monochrome sensor as second lens and 8MP 1/4" RGB sensor with 3x optical zoom as third lens.bokeh image with larger high dynamic range, whereas combination of mega pixel first lens and optical zoom will produce maximum 5x digital zoom without loss of quality by reducing the image size to 8MP.
After a big dip of sales in 2012, consumer digital camera sales declined again in 2013 by 36 percent. In 2011, compact digital cameras sold 10 million per month. In 2013, sales fell to about 4 million per month. DSLR and MILC sales also declined in 2013 by 10–15% after almost ten years of double digit growth.
Film camera sales hit their peak at about 37 million units in 1997, while digital camera sales began in 1989. By 2008, the film camera market had died and digital camera sales hit their peak at 121 million units in 2010. In 2002, cell phones with an integrated camera had been introduced and in 2003 the cell phone with an integrated camera had sold 80 million units per year. By 2011, cell phones with an integrated camera were selling hundreds of millions per year, which were causing a decline in digital cameras. In 2015, digital camera sales were 35 million units or only less than a third of digital camera sales numbers at their peak and also slightly less than film camera sold number at their peak.
Early cameras used the PC serial port. USB is now the most widely used method (most cameras are viewable as USB mass storage), though some have a FireWire port. Some cameras use USB PTP mode for connection instead of USB MSC; some offer both modes.
Other cameras use wireless connections, via Bluetooth or IEEE 802.11 Wi-Fi, such as the Kodak EasyShare One. Wi-Fi integrated Memory cards (SDHC, SDXC) can transmit stored images, video and other files to computers or smartphones. Mobile operating systems such as Android allow automatic upload and backup or sharing of images over Wi-Fi to photo sharing and cloud services.
Cameras with integrated Wi-Fi or specific Wi-Fi adapters mostly allow camera control, especially shutter release, exposure control and more (tethering) from computer or smartphone apps additionally to the transfer of media data.
Cameraphones and some high-end stand-alone digital cameras also use cellular networks to connect for sharing images. The most common standard on cellular networks is the MMS Multimedia Messaging Service, commonly called "picture messaging". The second method with smartphones is to send a picture as an email attachment. Many old cameraphones, however, do not support email.
A common alternative is the use of a card reader which may be capable of reading several types of storage media, as well as high speed transfer of data to the computer. Use of a card reader also avoids draining the camera battery during the download process. An external card reader allows convenient direct access to the images on a collection of storage media. But if only one storage card is in use, moving it back and forth between the camera and the reader can be inconvenient. Many computers have a card reader built in, at least for SD cards.
Many modern cameras support the PictBridge standard, which allows them to send data directly to a PictBridge-capable computer printer without the need for a computer.
An instant-print camera, is a digital camera with a built-in printer.instant camera which uses instant film to quickly generate a physical photograph. Such non-digital cameras were popularized by Polaroid with the SX-70 in 1972.
Many digital cameras include a video output port. Usually sVideo, it sends a standard-definition video signal to a television, allowing the user to show one picture at a time. Buttons or menus on the camera allow the user to select the photo, advance from one to another, or automatically send a "slide show" to the TV.
Some DVD recorders and television sets can read memory cards used in cameras; alternatively several types of flash card readers have TV output capability.
Cameras can be equipped with a varying amount of environmental sealing to provide protection against splashing water, moisture (humidity and fog), dust and sand, or complete waterproofness to a certain depth and for a certain duration. The latter is one of the approaches to allow underwater photography, the other approach being the use of waterproof housings. Many waterproof digital cameras are also shockproof and resistant to low temperatures.
Some waterproof cameras can be fitted with a waterproof housing to increase the operational depth range. The Olympus "Tough" range of compact cameras is an example.
Many digital cameras have preset modes for different applications. Within the constraints of correct exposure various parameters can be changed, including exposure, aperture, focusing, light metering, white balance, and equivalent sensitivity. For example, a portrait might use a wider aperture to render the background out of focus, and would seek out and focus on a human face rather than other image content.
Vendors implement a variety scene modes in cameras" firmwares for various purposes, such as a "landscape mode" which prevents focusing on rainy and/or stained window glass such as a windshield, and a "sports mode" which reduces motion blur of moving subjects by reducing exposure time with the help of increased light sensitivity. Firmwares may be equipped with the ability to select a suitable scene mode automatically through artificial intelligence.
Many camera phones and most stand alone digital cameras store image data in flash memory cards or other removable media. Most stand-alone cameras use SD format, while a few use CompactFlash or other types. In January 2012, a faster XQD card format was announced.hot-swappable memory slots. Photographers can swap one of the memory card with camera-on. Each memory slot can accept either Compact Flash or SD Card. All new Sony cameras also have two memory slots, one for its Memory Stick and one for SD Card, but not hot-swapable.
The approximate count of remaining photos until space exhaustion is calculated by the firmware throughout use and indicated in the viewfinder, to prepare the user for an impending necessary hot swap of the memory card, and/or file offload.
A few cameras used other removable storage such as Microdrives (very small hard disk drives), CD single (185 MB), and 3.5" floppy disks (e. g. Sony Mavica). Other unusual formats include:
Onboard (internal) flash memory — Cheap cameras and cameras secondary to the device"s main use (such as a camera phone). Some have small capacities such as 100 Megabytes and less, where intended use is buffer storage for uninterrupted operation during a memory card hot swap.
Most manufacturers of digital cameras do not provide drivers and software to allow their cameras to work with Linux or other free software.USB mass storage and/or Media Transfer Protocol, and are thus widely supported. Other cameras are supported by the gPhoto project, and many computers are equipped with a memory card reader.
Many cameras, especially high-end ones, support a raw image format. A raw image is the unprocessed set of pixel data directly from the camera"s sensor, often saved in a proprietary format. Adobe Systems has released the DNG format, a royalty-free raw image format used by at least 10 camera manufacturers.
Other formats that are used in cameras (but not for pictures) are the Design Rule for Camera Format (DCF), an ISO specification, used in almost all camera since 1998, which defines an internal file structure and naming. Also used is the Digital Print Order Format (DPOF), which dictates what order images are to be printed in and how many copies. The DCF 1998 defines a logical file system with 8.3 filenames and makes the usage of either FAT12, FAT16, FAT32 or exFAT mandatory for its physical layer in order to maximize platform interoperability.
Most cameras include Exif data that provides metadata about the picture. Exif data may include aperture, exposure time, focal length, date and time taken. Some are able to tag the location.
The filesystem in a digital camera contains a DCIM (Digital Camera IMages) directory, which can contain multiple subdirectories with names such as "123ABCDE" that consist of a unique directory number (in the range 100...999) and five alphanumeric characters, which may be freely chosen and often refer to a camera maker. These directories contain files with names such as "ABCD1234.JPG" that consist of four alphanumeric characters (often "100_", "DSC0", "DSCF", "IMG_", "MOV_", or "P000"), followed by a number. Handling of directories with possibly user-created duplicate numbers may vary among camera firmwares.
To enable loading many images in miniature view quickly and efficiently, and to retain meta data, some vendors" firmwares generate accompanying low-resolution thumbnail files for videos and raw photos. For example, those of Canon cameras end with .THM.
Digital cameras have become smaller over time, resulting in an ongoing need to develop a battery small enough to fit in the camera and yet able to power it for a reasonable length of time.
The most common class of battery used in digital cameras is proprietary battery formats. These are built to a manufacturer"s custom specifications. Almost all proprietary batteries are lithium-ion. In addition to being available from the OEM, aftermarket replacement batteries are commonly available for most camera models.
Digital cameras that utilize off-the-shelf batteries are typically designed to be able to use both single-use disposable and rechargeable batteries, but not with both types in use at the same time. The most common off-the-shelf battery size used is AA. CR2, CR-V3 batteries, and AAA batteries are also used in some cameras. The CR2 and CR-V3 batteries are lithium based, intended for a single use. Rechargeable RCR-V3 lithium-ion batteries are also available as an alternative to non-rechargeable CR-V3 batteries.
When digital cameras became common, many photographers asked whether their film cameras could be converted to digital. The answer was not immediately clear, as it differed among models. For the majority of 35 mm film cameras the answer is no, the reworking and cost would be too great, especially as lenses have been evolving as well as cameras. For most a conversion to digital, to give enough space for the electronics and allow a liquid crystal display to preview, would require removing the back of the camera and replacing it with a custom built digital unit.
Many early professional SLR cameras, such as the Kodak DCS series, were developed from 35 mm film cameras. The technology of the time, however, meant that rather than being digital "backs" the bodies of these cameras were mounted on large, bulky digital units, often bigger than the camera portion itself. These were factory built cameras, however, not aftermarket conversions.
A few 35 mm cameras have had digital camera backs made by their manufacturer, Leica being a notable example. Medium format and large format cameras (those using film stock greater than 35 mm), have a low unit production, and typical digital backs for them cost over $10,000. These cameras also tend to be highly modular, with handgrips, film backs, winders, and lenses available separately to fit various needs.
The very large sensor these backs use leads to enormous image sizes. For example, Phase One"s P45 39 MP image back creates a single TIFF image of size up to 224.6 MB, and even greater pixel counts are available. Medium format digitals such as this are geared more towards studio and portrait photography than their smaller DSLR counterparts; the ISO speed in particular tends to have a maximum of 400, versus 6400 for some DSLR cameras. (Canon EOS-1D Mark IV and Nikon D3S have ISO 12800 plus Hi-3 ISO 102400 with the Canon EOS-1Dx"s ISO of 204800).
In the industrial and high-end professional photography market, some camera systems use modular (removable) image sensors. For example, some medium format SLR cameras, such as the Mamiya 645D series, allow installation of either a digital camera back or a traditional photographic film back.
Most earlier digital camera backs used linear array sensors, moving vertically to digitize the image. Many of them only capture grayscale images. The relatively long exposure times, in the range of seconds or even minutes generally limit scan backs to studio applications, where all aspects of the photographic scene are under the photographer"s control.
Since it is much easier to manufacture a high-quality linear CCD array with only thousands of pixels than a CCD matrix with millions, very high resolution linear CCD camera backs were available much earlier than their CCD matrix counterparts. For example, you could buy an (albeit expensive) camera back with over 7,000 pixel horizontal resolution in the mid-1990s. However, as of 2004
Most modern digital camera backs use CCD or CMOS matrix sensors. The matrix sensor captures the entire image frame at once, instead of incrementing scanning the frame area through the prolonged exposure. For example, Phase One produces a 39 million pixel digital camera back with a 49.1 x 36.8 mm CCD in 2008. This CCD array is a little smaller than a frame of 120 film and much larger than a 35 mm frame (36 x 24 mm). In comparison, consumer digital cameras use arrays ranging from 36 x 24 mm (full frame on high end consumer DSLRs) to 1.28 x 0.96 mm (on camera phones) CMOS sensor.
I think that one of the best features of the Leica Q2 Monochrom is the EVF. Unlike the Leica M10 Monochrom, the EVF gives you the ability to preview an image before you press the shutter button. This is really helpful at times when you are not sure if an image would work in black and white. This not only helps with composition but with the exposure settings as well as the EVF gives you a representation of the overall exposure and you can quickly check your highlights and shadows and make sure you are happy with the exposure settings. From my brief amount of time with the Leica Q2 Monochrom sensor, protecting your highlights seems to be extremely important. You have almost no ability to recover overexposed areas of an image so you need to make sure you get your exposure correct. With a Leica M10 Monochrom, you would either have to use the backscreen and check the exposure before you click the shutter button or you would have to chimp afterward.
With these monochrome sensors from Leica, it is far better to underexpose an image than it is to blow the highlights and the Leica Q2M EVF means I can shoot the camera in aperture priority and use exposure compensation to control the exposure and protect my highlights as I am getting realtime feedback in the EVF. This is fantastic. It is exactly why I started to use EVF cameras at work as well. The
