Reviewers from cameralabs have found the following***:
Sony's Alpha A7r Mark III is a highly capable camera that's equally at home shooting high resolution stills as it is handling fast action or filming quality video. The 42 Megapixel full-frame sensor may be inherited from the Mark II but Sony's improved the processing to deliver superb quality. The ability to shoot at 10fps with confident autofocus makes it surprisingly good at sports, and great for events or wildlife shooting too with its silent shutter. Movie shooters will enjoy good quality 4k along with 1080 / 120p for slow motion, and the camera sports improved controls.

Pros
  • Excellent image quality
  • Excellent battery life
  • Easy to use
Cons
  • No interval timer
  • No USB Type-C

Sentiment Score 75%
Reviewers from pcmag have found the following***:
The a7R III doesn't offer increased resolution when compared with its predecessor. It takes a sensor that's already proven to deliver excellent performance and ekes a bit more dyanmic range out of it. Faster autofocus and burst shooting matter more, and improved battery life makes it a much more appealing option for professional use.

Pros
  • Excellent image quality
  • Fast autofocus
  • Excellent battery life
  • 4K video
  • 5fps burst shooting
Cons
  • Limited ISO range
  • No EVF

Sentiment Score 88%
Reviewers from t3 have found the following***:
Sony has taken the already excellent A7R II and made it even better. The sensor is a 42.2MP back-illuminated, full frame Exmor R CMOS. The rear tilt-angle display is improved too, with a resolution of 1.44 million dots. Autofocus is seriously better, with 400 detection points compared to the previous 25.

Pros
  • Superb autofocus
  • Good noise handling
  • Very good battery life
Cons
  • No XQD memory card slot
