Additional information:

The Helios-81 50 mm f/ 2 (Russian: "Гелиос") is a Kit lens for a 35mm SLR camera Kiev (Nikon F mount) and with М42 screw mount. Versions with the single and multicoating (MC) existed.

This lens was being manufactured by an "Arsenal" factory in different modifications: Helios-81-avtomat, Helios-81M, Helios-81N (russian letter looks like "H"). Later version was named ARSAT-H 50 mm f/2.

Also there was released sample quantity of Helios-81 52 mm f/2 at KMZ factory with a 12-blade diaphragm and minimum focusing distance 0.4 m.

Personally, i have seen Helios-81H in two modifications. It is interesting that a focal length differs in a short range if you inspect lens labeling for several samples.

This lens has a "swirly bokeh" (background looks like being twisted) but such effect is lighter than with Helios-40 or Helios-44.

According to D.Volosov (russian famous optics specialist) resolution of this lens is (center/10mm/20mm): 52, 37, 27 lp/mm.

Period of use: 36 months

Strengths:

Good USSR IQ -- it has the USSR glass look. In fact, color match between my old USSR lenses is surprisingly good. Really tiny (in Kiev 10/15 mount).

Weaknesses:

Build is solid, but a little coarse.

Comments:

Mine is in Kiev 10/15 mount, used on Sony E bodies via a 3D printed adapter.
