Well i just picked up this little gem in NYC the past week and i wanted to post samples for others to see.I used the lens for nearly an entire week on my NEX 5N with M39 Mount adapter.My overall impression of the lens is - OUTSTANDING in all areas.
-Center sharpness WO is as sharp as any 1.4 i have used if not sharper.
Contrast and Color are excellent and responds very well in Post Processing.
-Infinity focus is extremely sharp stopped down just a little.
Over all IMO Very impressive little lens when you consider its likely 70 years old.
Here are a few to look at.Will post more later

Attila,
these are the same photos i posted earlier.I can take other pictures of the lens if you would like.It is a very small lens.Definitely was made for a Leica rangefinder.

remounted lens, barel is not made by Jena. I have this lens too an optical block only, require remount.

I only know these two lenses.

It likely is a remounted lens, but i do not think it was a Cine lens to begin with.The lens is very small and resembles closely this lens here, in fact the serial numbers are very close to each other http://www.liveauctioneers.com/item/2668043

Interesting rendering Smile I wonder how does it compare to Jupiter 3, they might have something in common...
