A Jupiter 9 lens (85mm focal length, f2 aperture) for the Contax rangefinder mount. This lens has 15 diaphragm blades (no oil on them).
The coatings on the lens are in good condition. There are some small visible specks of internal dust, but these will not affect a photograph. The focus is fairly firm in operation, but I think this may be as original designed.
It is supplied with a generic front lens cap, but no rear cap.
