Lens mount

Photo / Video

The mechanical and electronic interface where a lens attaches to a camera body — examples include Sony E, Canon RF, Nikon Z and the shared L-Mount. The mount handles both the physical coupling and the electronic communication for autofocus, aperture and stabilization. For a lens to work fully it generally has to be made for the body's mount, or be fitted with an adapter (and some adapters limit autofocus or other features). Concrete example: a Canon RF lens won't natively fit a Sony E body, and vice versa. Buying impact: the mount is the first thing to check when buying glass, because it determines which lenses you can use today and how easily you could switch systems later — making it one of the most consequential long-term decisions in a camera kit.
