Jupiter-11, 135/4, SLR Mount


The Russian Jupiter-11 is a high quality telephoto lens. It was made in many different mounts - some are well-known standard (Leica, Contax), some are specific (Kiev-10 etc.). It is an optical copy of the prewar Zeiss Sonnar 135/4.

This Jupiter-11 was made for the early Zenit SLRs (Zenit, Zenit-S, Zenit-3, Zenit-3M, Kristall), but its optical registration (back focus) is the same as in the Universal Pentax Screw Mount (M42), so with a simple 39 to 42 mm adapter ring (not included) the lens can be used with any 42 mm Pentax Screwmount camera.
