Sony NEX5, no pp, in-camera profile "Vivid"
Sorry for blown highlights in #2, it was only discovered later.
Just for reference - this is not Helios-40 or 44, the key clue is that lens of this optical formula rarely were made for 16mm, and rarely with such fast aperture.

Nearly impossible except for just a few very unique lenses. This one looks like a projector lens by the very shallow DOF and circular distortion. I'll guess something like a 1.8/140

It is much faster than 1.8 and much shorter than 140 
And it does not use petzval scheme, often used in projector lenses

I will say it does not look like the 2.8/100 Diaplan I have, and that ends my experience with projector lenses.

Shot open aperture? |

Yes, shot at widest possible. Yes it is 50mm and yes it is cine lens but not one mentioned
Hint - it has 13 blade circular aperture....

Actually, RO-109 was quite close, since produces almost similar results, since uses almost similar optical scheme (pancolar) but this lens has aperture...
