Hello everybody,

Here is another share about soviet lenses. This time, it's an Helios-81M (in Nikon mount, for Kiev-19) made by Arsenal, mounted on A7. Diagram is not exactly like helios-44.

I also have a helios 81, but yours looks sharper and better. Mine has glow around highlighs, and is probably compromised somehow.

Nice rendering again. The second image of the yellow Lada also shows quite a lot 3d pop for me. Do you remember the F-stop? And where did you focus to achieve this level of sharpness?

Is this lens a copy of any 50mm Nikkor?

The designs are similar, but I won't say it's a copy. It's a typical Double Gauss design.
