Sony Alpha 7R III + Sony FE 24-70mm f/4 ZA OSS Vario-Tessar T*
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.
4.weight
675g
673g
We consider a lower weight better because lighter devices are more comfortable to carry. A lower weight is also an advantage for home appliances, as it makes transportation easier, and for many other types of products.
5.viewfinder coverage
100%
100%
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
1.sensor size
24 x 35.9mm
35.6 x 23.8mm
The larger the sensor the more light the sensor captures yielding in better image quality.
2.focus points
425
693
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.
3.megapixels (main camera)
42.4MP
24.2MP
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.
4.maximum light sensitivity
102400 ISO
204800 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.
5.continuous shooting at high resolution
10fps
20fps
Fast continuous shooting is useful for catching action shots.
6.has AF tracking
Sony Alpha 7R III + Sony FE 24-70mm f/4 ZA OSS Vario-Tessar T*

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
1.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.
2.Has phase-detection autofocus for videos
Sony Alpha 7R III + Sony FE 24-70mm f/4 ZA OSS Vario-Tessar T*
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.
3.has continuous autofocus when recording movies
