In addition to Zeiss lenses for Contax RF, Nikon also made lenses for this mount. Many Russian lenses were also made to fit. Be aware that some lenses that fit the pre-War Contax, like the 35/2.8 Biogon, will not fit the post-War IIA and IIIA - their rear element protrudes too deeply into the body. Standard Nikon RF mount lenses will attach to a Contax, but may not focus accurately with 50mm and longer lenses. Nikon's lenses that were made for Contax will have a "C" engraved on the underside of the barrel. 35mm and wider Nikon lenses work fine on Contax bodies.
