Just got hold of an Isco Gottingen Tele-Westanar 135mm f3.5 that looks kind of interesting to play with. Its got 15 blades and I thought I'd like to try it on my Oly EM5 or OM1 but I'm not sure what mount it is. I know that some are in Exa, Edixa fit and M42 but this doesnt seem to be either. There is a thin ring at the rear which looks to be threaded and is the diameter of the lens, about 49mm. This looks more like a locking ring, perhaps to hold a mount.
Anyway, I have faith in you guys having the answer, no pressure then🙂
