Best camera for the canon rf 5 2mm f 2 8l dual fisheye?
The Canon RF 5.2mm f/2.8L Dual Fisheye is a full-frame lens, so I'd pair it with a full-frame body. It's manual focus only, so choose a camera whose viewfinder and controls you like for focusing by hand.
From the lens's list, I'd start with these:
- Canon EOS R6 Mark II: my all-round pick here, a sensible full-frame body for this kind of shooting.
- Canon EOS R5: the one to consider if you want more resolution for large prints.
- Canon EOS R8: a lighter full-frame option if you carry your kit a lot.
If you're tempted by an APS-C body such as the Canon EOS R7, the lens frames tighter there, so read Sensor sizes first.
