The Sony α7R III (model ILCE-7RM3)[2] is a full-frame mirrorless interchangeable-lens camera manufactured by Sony. It was announced on 25 October 2017 as the successor to the Sony α7R II launched two years prior. The camera shares many features with the α7R II, including the same 42.2 MP resolution for still photography. It was superseded by the Sony α7R IV in July 2019.
The camera does not include an optical low-pass (anti-aliasing) filter.[3]

Improvements over α7R II
Several improvements were made compared to the α7R II, including the following:[2]
- Improved dynamic range due to lower noise in sensor readout
- 425 contrast-detect autofocus points, up from 25 in the α7R II
- Altered button layout reminiscent of the α9
- Improved autofocus performance
- Improved battery life due to larger battery
- Dual SD card slots, compared to a single slot in the α7R II. However, the slots do not exactly match. One is an SD slot (UHS-I/II compliant), the other is a dual SD (UHS-I compliant) and Sony Memory Stick Duo slot.
- Improved shutter mechanism to reduce shutter-induced shake
- Pixel shift multi-shot mode that combines exposures taken on each subpixel of the Bayer filter, improving overall image quality
