Our Verdict

Sony α7 III

Sony α7R IIIa

The Sony α7 III and the Sony α7R IIIa are both great full-frame cameras from the same generation. They're similar in build quality, design, and ergonomics, but the α7R IIIa uses a higher-resolution sensor that makes it a better fit for photography, whereas the α7 III is more of a hybrid photo/video camera, with better rolling shutter performance and a more reliable autofocus system. The α7R IIIa also has a few minor hardware advantages, including weather-sealing and a higher-resolution screen and EVF.
