Russian Jupiter-3
lens in Contax RF Mount
This lens is a copy of the famous
Zeiss Sonnar 50/1.5. It was initially made for the Kiev line in Contax/Kiev
bayonet mount and later - in Leica thread mount. The lens is sharp and
contrasty, and even at maximum aperture produces great images.

This Jupiter-3 was made
in the mid-1950's. The lens is in EXC.- condition. The barrel finish is clean, no
brassing. The glass is also clear and clean, with a few faint cleaning marks
on the front element (they are present on practically every Jupiter-3 lens).
The lens comes with the front lenscap and a plastic case.
The Jupiter-3 is uncommon; it
was sold as a separate interchangeable lens. I believe it never came as
a standard Kiev RF equipment.
The lens is shown mounted on a
Contax II (not included).
