KMZ Helios-40 85mm f1.5 M39

A classic Russian lens, especially known for its "dreamy" bokeh.
M39 screw mount, but can be adapted to almost anything you want. A popular lens among both filmmakers and still photographers. It has a stepless aperture.

It has just been serviced, with the focusing re-greased and the aperture blades cleaned. The aperture blades show some wear (see pictures).
Includes original brown leather case, a lightly toned yellow filter, and front cap (no rear cap).
