Seems to be an impressive lens, John. I like the rendering of colors and the bokeh even more!
Thanks for sharing! I am looking forward to seeing morr!

well done! Personally I prefer the older version which is an apertureless Helios 40-2 f1.5/85mm
formerly known as kds315

Very nice lens John!
1,3 the most preferable, it reminds me the rendering of my  Helios 58/2 they are very good lenses even wide open and the absence of modern coatings gives the photo a kind of magic  :)

Thanks for your remarks and comments

Personally I prefer the older version which is an apertureless Helios 40-2 f1.5/85mm
By fortune I got this one for a few euro. 
Later I read about the Helios 85mm.   100mm f/2 is also very nice ;)

Very little chromatic aberration. There is central sharpness, where the edges become vague,  but if you move the focus to the edge of the lens, a kind of PC effect is created. (DOF curvature)

I also got a selection of old CCCP lenses. Most in M39 and Contax mount. Yet a reason to get a Z-body to get infinity focus.
Also many Jupiter lenses can be fun to try like Jupiter 3, 8 and 9.....

Yes that sounds like fun ;)   A good Z body is an advantage for all kind of these lenses.  More and better adapters are coming now on the market.

The origin of the lens is  a night vision device. 

Here is some you-tube-info, but with 85mm 1.5 lens.
