Condition 97%. Lovely example of this rare Proxar close-up lens combination from Zeiss for Contax rangefinder cameras. In 30 years of selling this is the first of these we've seen. The viewing part mounts to the Contax lens mount, offering correctly aligned close-up rangefinder focusing at 1m, the taking lens is 40.5mm screw mount and mounts on the lens. rare and beautiful outfit.
