Contax N mount lenses

Contax N mount

Contax N mount is a fully electronic, autofocus lens mount designed for 35mm SLR cameras by Carl Zeiss and Kyocera in 2000. It is a bayonet mount with three tabs, a focal flange distance of 48mm, and an unusually large throat diameter of 55mm. Despite the lenses having a physical aperture ring, it is a fully electronic mount with no mechanical connections. Contax N lenses could be mount-swapped to Canon EF mount, with replaced electronics, all the functionality can be retained, as well.

The system consists of nine lenses in total, there is a genuine Contax NAM-1 adapter for using Contax 645 lenses which retains all functions, including the autofocus.

Contax N lens system was officially discontinued by Kyocera in 2005.
