Sony a7r iii vs sony a7r ii?
The a7R II and a7R III are close cousins. Both are full-frame Sony E-mount mirrorless cameras with 42.4 megapixels and in-body stabilisation. The Sony a7R II was announced in 2015, and the Sony a7R III followed in 2017. The a7R III was also sold from 2021 as the a7R IIIA, which has a sharper rear screen.
Because they share a mount, every lens on one fits the other. For a sensible everyday kit, I'd pair either body with the Sony FE 24-70mm f/2.8 GM II, the Sony FE 16-35mm f/2.8 GM II, or the Sony FE 70-200mm f/2.8 GM OSS II.
If you want more resolution rather than a newer body, the Sony a7R IV offers 61 megapixels.
