Hello,
Here are some photos I took with a rare soviet TV lens OT-1 40/2.8. I have no idea what is the optical construction, but it is definitly not a planar design regarding to rear working distance (relatively long distance for a 40mm lens). There isn't any other 40mm/2.8 in the soviet industry. It was made in 1963 for a prototype TV camera. All shot wide open.

Wonderful bokeh. Looks like it overexposes easily?

Dreamy look, I like it! It could be a Sonnar-like design. |

No, it's my bad, my finger was too heavy on the exposure cursor  .

Thanks for the hint, I will take a look on this Sonnar idea.

Tasty pictures and tasty berries! 
I especially like the bokeh in those flower shots! It looks like there's a hard vignette that grows with increased focus distance. On what format were these shot?
