Thanks for your comments!

Jacques, I bought this one on Aukro (which is closed now, btw) some months ago. Usualy it's opposite, seen first localy, and then on ebay

. So I believe it's different one.
Guido, to my eyes, there is nothing special about perspectives on the 3rd one. This day, I also used a Mir-47K 20/2.5, I don't think it was done with wide angle. All I can say is that it's straight from the scan, exepted crop (explaination at the end of the message

). I should remove dust, but I'm sometime a bit lazy.
I'm a bit opposite, I'm not a camera collector, I initialy collecting soviet lenses only, and used them on digital Sony A7. But last months, I decided to use film camera. I bought some cameras in order to use the most of my lenses. I always try to find the most practical (automat or at least TTL) or with the best viewfinder, no collecting wish here.

I have actualy :
Zorki-4 for LTM (Leningrad has great viewfinder, but it's pretty to hard or pricy to find a working one)
Zenit-19 for M42
Kiev-5 for external kiev mount, Jupiter-8NB and Helios-94
Zenit Automat for K mount lenses
Kiev-6C for MF lenses and aerialphoto lenses
Incoming :
Kiev-15 TEE for my Automat lenses
Kiev-19 for my arsenal Nikon mount lenses
Start for Z39 (via adapter)
Btw, this Zenit automat is not working good, a problem with pentaprisme. If I take a photo, what I see in viewfinder is not what will be on final photo, it will be upper (so in many photo, I have too much sky). Quite frustrating, and need to crop to find a better composition. I'm working on it with master from ukraine and a french friend. Soon or later, I will solve it. The mirror is OK (45°).
