Best camera for the 7artisans 9mm f 5 6?
The 7Artisans 9mm f/5.6 is a full frame lens, so it's happiest on a full frame body, where it gives its true 9mm view. For an everyday kit, I'd pick the Sony a7 III. It's a sensible all-rounder for a manual-focus lens like this one. Nikon Z shooters could go with the Nikon Z6 II, and Canon shooters with the Canon EOS R6 Mark II.
You can also use it on an APS-C body, such as the Sony a6700, but it then frames like 14mm on full frame. That's still wide, just less dramatic. If you're not sure what the crop means, the sensor sizes guide explains it.
