Anyone ever seen this lens? (adapted to Kiev-60 mount)
Any clue about what is it for? I found nothing on the runet... Surely technical, but for what? It's quite heavy (2.8kg), big. Acutualy no diaphragme, but I suspect there was a diaphragm before.
OB is known to be a code name for lenses (more commonly is OF).
Thanks for you answer, but it doesn't help me a lot. The first link to the sale is the one I bought The seller told it's space photographie, but I rarely believe to this. He is old and very gentle, but I'm not sure he was competent about soviet lenses. The second one is about J-48, it's another lens. Same for J-25...there are a lot of J-XX lenses, it's cine lenses and projector lenses.
