Best camera for the canon rf s 14 30mm f 4 6 3 is stm pz?
The easiest pick is the Canon EOS R50 V. It's sold as a kit with this lens, and it's an APS-C body, so the lens frames the way it was designed to, at full resolution.
If you want a bit more camera, the Canon EOS R10 and Canon EOS R7 are also APS-C and work with this lens natively.
Full-frame bodies such as the Canon EOS R6 Mark II will take it too, but only in APS-C crop mode, which gives up resolution. I'd only go that way if you already own one.
To see how the crop changes the field of view on any of these, try the Focal length converter.
