Anyone know who made this one? It seems pretty sharp, which is the main point, but I'm a nerd and I like to know as much info about a lens as possible.
I had one with s/n 52525. It appears that many of them were made. I wouldn't be suprised if it was made by Asahi Pentax, but I've never found anything about that. I think that mine had fewer things written on the front plate, but I can't find any photos of it.
