Starting with image quality, the A7R share the same body as the A7R II, with Sony resisting the urge to make wholesale changes, but Sony has found room for a focus point selection joystick, AF-On button, dual SD card slots, flash sync socket and a bigger capacity battery into the same design. The new camera also gets the 3.69M-dot OLED viewfinder from the a9, providing a 1280 x 720 resolution view. This gives you highly detailed images with high contrast and deep blacks through the EVF, particularly during playback.
Sony Alpha A7R III Speed:-
Starting with the main bits, the sensor in the new A7R III is the same 42.2-megapixel BSI CMOS sensor, but a series of hardware and processing changes act to get more out of it.

There’s 5-axis image stabilization in the body itself, which offers 5.5 step shutter speed advantage.The screen is also now touch-sensitive and there’s both USB-2 and USB-C / 3 ports, allowing you to power the camera with one and tether with the other if desired. Like the A9, there’s no PlayMemories apps, so you’ll be looking to a third party for an intervalometer.

The camera's Is mechanism also gets a boost with the 5-axis image stabilization in the body itself, which upgraded to receive a 5.5 step rating, by CIPA standard testing. The full capabilities of the system remain available in video shooting.

These four images can be composited together and processed utilizing the new Imaging Edge software suite.
