Unknown. Help us by suggesting a value. (Sony Alpha a9 + Sony FE 24-70mm F2.8 GM)

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.
Has a built-in focus motor
Sony Alpha 7R III
Sony Alpha a9 + Sony FE 24-70mm F2.8 GM
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.
Has a flip-out screen
Sony Alpha 7R III
Sony Alpha a9 + Sony FE 24-70mm F2.8 GM
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 bigger the screen size is, the better the user experience.
is dustproof and water-resistant
Sony Alpha 7R III
Sony Alpha a9 + Sony FE 24-70mm F2.8 GM
The device is dustproof and water-resistant. Water-resistant devices can resist the penetration of water, such as powerful water jets, but not being submerged into water.

Optics

sensor size

Full frame

Full frame

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.
maximum light sensitivity

Unknown. Help us by suggesting a value. (Sony Alpha 7R III)

Unknown. Help us by suggesting a value. (Sony Alpha a9 + Sony FE 24-70mm F2.8 GM)

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.
maximum expanded ISO

102400ISO

204800ISO

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.
has sensor shift stabilization
Sony Alpha 7R III
Sony Alpha a9 + Sony FE 24-70mm F2.8 GM
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.
Fast continuous shooting is useful for catching action shots.
has AF tracking
Sony Alpha 7R III
Sony Alpha a9 + Sony FE 24-70mm F2.8 GM
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.
Has phase-detection autofocus for photos
Sony Alpha 7R III
Sony Alpha a9 + Sony FE 24-70mm F2.8 GM
Phase-detection autofocus is much faster than a contrast detection autofocus, allowing for sharper images.

Videography

video recording (main camera)

2160 x 30fps

2160 x 30fps

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.
Has phase-detection autofocus for videos
Sony Alpha 7R III
Sony Alpha a9 + Sony FE 24-70mm F2.8 GM
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.
has continuous autofocus when recording movies
Sony Alpha 7R III
Sony Alpha a9 + Sony FE 24-70mm F2.8 GM
When recording movies they stay focussed and sharp.
has a microphone input
Sony Alpha 7R III
Sony Alpha a9 + Sony FE 24-70mm F2.8 GM
A microphone port allows connecting external high-end or specialized microphones.
has a socket for a 3.5 mm audio jack
Sony Alpha 7R III
Sony Alpha a9 + Sony FE 24-70mm F2.8 GM
With a standard mini jack socket, you can use the device with most headphones.
has a stereo microphone
Sony Alpha 7R III
Sony Alpha a9 + Sony FE 24-70mm F2.8 GM
A stereo microphone allows to record audio files or movies in stereo without an external microphone.
Has timelapse function
Sony Alpha 7R III
Sony Alpha a9 + Sony FE 24-70mm F2.8 GM
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

Unknown. Help us by suggesting a value. (Sony Alpha 7R III)

100Mbps

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.

Has dual card slots
Sony Alpha 7R III
Sony Alpha a9 + Sony FE 24-70mm F2.8 GM
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.
shoots raw
Sony Alpha 7R III
Sony Alpha a9 + Sony FE 24-70mm F2.8 GM
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.
supports lossless compressed raw
Sony Alpha 7R III
Sony Alpha a9 + Sony FE 24-70mm F2.8 GM
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.
has pixel shift shot
Sony Alpha 7R III
Sony Alpha a9 + Sony FE 24-70mm F2.8 GM
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.
