Minolta rokkor 85/1,7 MC & Konica Hexanon 85/1,8 AR EE

All shot wideopen, no different between f1,7 and 1,8 in speed on my NEX5
First Minolta, 2nd is Konica

Schneider Kreuznach Xenon 50/1,9 Exakta

I've been looking for this lens for such a long time, now I have it in exakta mount.
There're some version of this Xenon. Silver, black, zebra. and various mount too. I read somewhere that coating is different for each version.
All shot wide open

Different kind of bokeh

Minolta Rokkor 85/1,7 MC

I have an opportunity to test this lens. excellent condition. little bit soft at wideopen, but detail appear clearly.
start sharp at f2,8

Infinity tes

wideopen

Cosmicar 75/1,4 Television c mount

Some c mount lenses has swirly bokeh. this one has it too.
strange type bokeh. not so sharp at wideopen. good for portrait I guess.
Dont expect sharpness in corners, in my experience, no c mount lenses have it. IMHO. well maybe untill  someday I found different one.
It's not easy to find right focus, specially wide open. but not difficult either. you just need to practice, and you will find pleasing result,

wideopen, Remind me of Meyer Optik Trioplan 100/2,8

f2,8

f1,4, remind me of Biotar or Helios

f1,4
