I had an East German camera (a Praktica) for a short while; my aunt brought it with her from England. Seeing the comments about Soviet build quality, I'd note that it also applies to Soviet satellites as well. The lens was wonderful, but it didn't take many rolls of film for the shutter to give out. I switched to a Minolta SRT202 after that, before I ditched film for digital. I suppose I could have gone with a Pentax…
However, my understanding is Soviet designs used both mounts. Just clarifying not arguing. Out of a fondness for Pentax and tendency to geek.
