Hanimex's wide-angle for Chinon/Ricoh — the 28mm f/2.8 in NC1000 mount.
The Hanimex 28mm f/2.8 NC1000 Fit is a wide-angle prime from Hanimex specifically designed for the Nikon L35AF NC1000 (Nikon EM/FG system) cameras, which used a specific bayonet that differed from the standard Nikon AI mount. The NC1000 Fit is a proprietary coupling for Nikon's compact automatic cameras of the period.
The lens delivers 28mm at f/2.8 maximum aperture with the NC1000 proprietary bayonet, manual focus and aperture, and a wide-angle field of view suited to the compact camera system it was designed for.
The NC1000 (or AI-S compatible Nikon compact system) mount is an unusual variant that limits this lens's adaptability to cameras equipped with the specific NC1000 coupling. This is a niche product with limited modern utility outside of compatible Nikon compact SLR bodies.
Verify the NC1000 mount coupling against the intended camera body. Test aperture ring operation. Inspect elements for clarity. Note the limited adapter availability for the NC1000 mount format to modern cameras.
