Sony a7R III Review
The Sony a7R III ($3,199.99, body only) uses the same sensor as the a7R II that came before it, but just about everything else has changed. The image processor and circuitry that drives it are new, which improves dynamic range. The processor also drives a new autofocus system, which allows the camera to track moving action at 10fps—at 42MP resolution. Add a high-capacity battery, improved handling, and a larger viewfinder, and you have a full-frame mirrorless camera that is as formidable as competing SLRs. It delivers outstanding images, video, and autofocus, enough to earn our Editors' Choice. But some missing features keep it from getting the five-star rating we gave to its closest rival in the SLR world, the Nikon D850.
Design
The a7R III ($2,298.00 at Amazon) looks and feels a lot like the a7R II—they use the same chassis. It measures 3.8 by 5.0 by 2.9 inches (HWD) and weighs 1.5 pounds. The body is protected against dust and splashes, as are all Sony FE lenses.
