OOF areas are looking unique.
Could you tell us more about the lens? What was its intended use?

A Hamamatsu 3.5/50mm they have made for their intensified cameras. Don't look up the price please Wink

Nope, I got it used!! And it is for UV work mainly, not for visible light shots (but does well).

P.S. here is a test I made: http://photographyoftheinvisibleworld.blogspot.de/2012/10/hamamatsu-a4869-uv-lens-f3550mm-for.html showing that it is not that easy to use, best for lab use.

I did too. Suffice to say the price I saw was nearly as many feet as in a mile!

These images are fantastic real! Colors seem perfect.

Lens has a stunning clean UV/VIS transmission spectrum
Is it uncoated?

Yep, list price is crazy high for an uncoated lens.
