I have got a lens, but I can't find any info about it on the net, even on the .ru . Does anyone know when was it made, who made it and what for?
No factory logo, SN 3001. According to design, it's post 80's, maybe post-USSR. Surely for kind of automatic machine (regarding to cranted diaph ring). But only hypotheses, I thought one of you could have infos about this lens.
