The type of camera.
The type of viewfinder that the camera has.
The device is protected with extra seals to prevent failures caused by dust, raindrops, and water splashes.
A higher screen resolution provides a sharper image, making it easier to review your photos.

Sony A330 DSLR: Not applicable
Unknown. Help us by suggesting a value. (Sony Alpha 7)
An electronic viewfinder (EVF) with a higher resolution provides a sharper image, producing a view comparable in quality with the one displayed on an optical viewfinder.
The focus motor moves the lens in order to autofocus. For system cameras, having a focus motor in the camera's body allows you to use a wide range of lenses, including lenses which do not have their own focus motor. For compact cameras, a focus motor is usually built-in.
Flip-out screens can be useful for tricky shots.
With 100% coverage, you can compose the image correctly when you capture the photo. With less than full coverage, you may have to crop your photos afterward to get them looking perfect.
The size of the screen (measured diagonally).
Optics
One of the most important aspects of a camera is the size of its sensor. A larger sensor will capture more light, which results in improved low-light performance, dynamic range, and general image quality.
The more focus points the more flexibility in picking which part of the scene to focus on. They also give the image sensor a better probability in identifying the right area of the scene to focus on in more automatic modes.
The number of megapixels determines the resolution of the images captured with the main camera. A higher megapixel count means that the camera is capable of capturing more details. However, the megapixel count is not the only important element determining the quality of an image.
With a higher light sensitivity (ISO level), the sensor absorbs more light. This can be used to capture moving objects using a fast shutter speed, or to take images in low light without using a flash.
Expanded ISO allows you to go beyond the native ISO. It does this by digitally enhancing the image output. The resulting image will have less quality than when staying within the native ISO range, but it can be useful in certain situations.
With sensor shift, the image sensor (rather than the lens) moves to counterbalance any vibration of the camera. This means the image will be stabilised regardless of what lens is being used.
The number of frames per second that can be captured in continuous drive mode when using the mechanical shutter.
With AF tracking, once you choose the subject and press the shutter release part way down, as the subject moves, the autofocus will follow it. No more out of focus shots.
Videography
The maximum resolution available for videos shot with the main camera. Although it may be possible to choose among other frame rates, those recordings usually have lower resolutions.
A phase-detection autofocus system is faster than a contrast detection autofocus system. Even when recording scenes with a lot of fast movements, the videos are sharp and clear.
When recording movies they stay focussed and sharp.
A microphone port allows connecting external high-end or specialized microphones.
With a standard mini jack socket, you can use the device with most headphones.
A stereo microphone allows to record audio files or movies in stereo without an external microphone.
A timelapse shows a long passage of time sped up. A series of photographs taken from the same position over a long period is joined together to create a short video. It is great way to capture things like the setting sun, or clouds moving across the sky.
movie bitrate

The higher the movie recording bitrate the better the movie quality with more and crispier details and less compression artifacts.
More microphones result in better sound quality and enable the device to filter out background noise.
Battery
CIPA is an independent, standard measurement that determines how many shots a camera can take before the battery dies.
The battery is removable and can be replaced by the user if broken.
The battery can be recharged and used over again.
An indicator shows you when the device has low battery.
Battery power, or battery capacity, represents the amount of electrical energy that a battery can store. More battery power can be an indication of longer battery life.
Features
The device can connect to Wi-Fi.
Bluetooth is a wireless technology that allows you to easily transfer data between different devices, such as smartphones, tablets and computers.
It has two memory card slots, allowing you to store more photos without switching cards. This is particularly useful on long shoots when you need more space.
The camera can take a series of shots, shifting the sensor slightly with each one. These can then be combined to create an extremely high-resolution image. It’s particularly useful for things like photographing artwork.
A raw image file contains minimally processed data from the image sensor. Raw files are so named because they are not yet processed and therefore are not ready to be printed or edited with a bitmap graphics editor.
It is capable of shooting stills in a lossless compressed raw format. This has all the advantages of shooting raw, while taking up much less storage space. The smaller file size also allows quicker read/write speeds.
The Wi-Fi versions supported by the device.
This technology allows the users to use their smartphone as a remote control for the device.
You can output high definition video and audio to a display. This could be an HDMI port, Mini HDMI port, or a USB-C port that supports HDMI.
Miscellaneous
Pixel density is a measurement of a screen's resolution, expressed as the number of pixels per inch (PPI) on the screen. A higher pixel density translates into more clarity and sharpness for the images rendered on the screen, thus improving the quality of the viewing experience.
