Quite surprisingly, the new Voigtländer company, owned by Cosina, also launched a new rangefinder body in 2002 using the Contax RF mount, called the Bessa R2C, together with a range of lenses in Nikon RF mount.
The other lenses mount on an external bayonet and have their own focusing ring, only the rangefinder coupling is done via the body's focusing ramp. So the standard lenses have no focusing ring of their own. There is a focusing helical built in the body and the standard lenses mount directly in that focusing ramp via an internal bayonet. This mount is in fact the combination of two bayonets. Nikon copied the mount for their own rangefinder cameras just after the war but, being this a voluntary difference or a simple mistake, their lens mount is slightly different and only the wide angle lenses are interchangeable, the standard and tele lenses having a wrong focus coupling. This mount was also used by the Kiev followers of the Contax, from the first models to the Kiev 5.
The Contax II and III used the same mount, as well as the postwar Contax IIa and IIIa models. The Zeiss Ikon Contax I introduced a new lens mount in 1932, today known as Contax rangefinder mount. Scanned by Geoff Harrisson ( Image rights)
