has a built-in focus motor
Sony Alpha 7 IV
Sony Alpha a7 III
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 7 IV
Sony Alpha a7 III
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.

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.
lens mount

Sony E

Sony E

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 ISO

51200 ISO

51200 ISO

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

204800 ISO

204800 ISO

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 7 IV
Sony Alpha a7 III
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.
has AF tracking
Sony Alpha 7 IV
Sony Alpha a7 III
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

video recording (main camera)

2160 x 60 fps

2160 x 30 fps

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 7 IV
Sony Alpha a7 III
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 7 IV
Sony Alpha a7 III
When recording movies they stay focussed and sharp.
has a microphone input
Sony Alpha 7 IV
Sony Alpha a7 III

Sony Alpha 7 IV
Sony Alpha a7 III
With a standard mini jack socket, you can use the device with most headphones.
has a stereo microphone
Sony Alpha 7 IV
Sony Alpha a7 III
A stereo microphone allows to record audio files or movies in stereo without an external microphone.
Has timelapse function
Sony Alpha 7 IV
Sony Alpha a7 III
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

600 Mbps

100 Mbps

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

Battery life (CIPA)

580 shots

610 shots

CIPA is an independent, standard measurement that determines how many shots a camera can take before the battery dies.
