The stock is over. Unknown lens turned out to be Mir-3V 3.5 / 65. Congratulations to the winner.
The essence of the action was as follows: determine with which lens the photos were taken in this promotion

Promotion number 4
Terms and Conditions: in the comments to this article, you need to specify a lens on which, in your opinion, everything is shot. Be sure to justify your conclusion in a few words... Also, do not forget to indicate your e-mail, which will be used to contact the winner. The promotion lasts until one of the participants guesses.
First who guesses the lens following the rules, receives a SLR Camera Zenit-TTL with Helios-44m 2.0 / 58 lens. Delivery in Ukraine by New Mail (warehouse). Participants from other countries can simply participate. Below is a view of the gift itself.
Tips: this is a damn expensive lens at the time of its release, shot on D700, added sharpness and contrast without cropping.
Here are the photos themselves, which should guess the lens:
1

Help to the project. Thanks for attention. Arkady Shapoval.
I wonder if this is MIR 3, then I think MIR 38 is not worse? (I bought 400gr for cheap, new, not used, with a dock in a box, VEGA plant, 1981 in ... ... I wanted to find an adapter for m42, or Pentax ... so I got 450g !!! ... ... I got angry and cut off an extension ring h3 from my hemp ... it's foggy outside, I'm waiting for the weather, can't wait to take test photos ... sorry for the flood :)
want to participate in other promotions ... do you receive updates by email?
These beautiful blue highlights, it's easy to look at, what other lenses do they have? preferably wider than 65.
It was (blue glare). The culprit was the OM-NEX adapter. It was cured by blackening the shiny surfaces of the adapter and the bayonet with a black felt-tip pen.
so what in the end? What lens? *
Judging by the number of photos, apparently you were VERY sorry to part with the camera
