Nikon F3. Just a beast of a camera. In production from 1980 to 2001, even after its replacements, the F4 and then F5 were brought to market. Solid, smooth, versatile. Everything one needs, and nothing more.
It's true that photographers have a way of fetishizing their gear. But it's fun to appreciate the craft and aesthetic of cameras, just like in these amazing studio portraits by photographer Julian Calverley.
