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

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.

John, next time we meet up we need to give our Helios lenses a spin ;)

Ah thanks Jakov. Good idea. 

Was that the 85/1.5 you have ?

yes, i have the 85/1.5, with an aperture ring, which is always at f/1.5 anyway ;)

I've owned both the Helios 40-2 85/1.5 and the Cyclop 85/1.5. The focus mechanism of the 40-2 is more nicely dampened than the Cyclop, but it is heavier as well, 880g versus 660g. Given that I only use it at f/1.5, I sold my 40-2.

You always have to come up with cool lenses and cooler images... ::)

  That looks like a lot of fun too

Thanks Paco. Sometimes you need to be lucky to find 'cool'  lenses ;)

Still testing the lens in the field

The central scene of the lens is pretty sharp. The outskirts have different focus settings for sharpening and give an unusual effect.

And apparently you can shoot through the plant, with this lens  ;)

Close focus on the stones on the center top of the image.  The rest is out of focus.

The lens seems to perform superbly on a m4/3 format camera as a fast 200mm equivalent.

Yes, that would give a sharp image over the whole sensor, I think
