So the Russians got ya...
Whenever I'm out with my Kiev (KNEB) I get some interesting comments. I've got a Kiev 4a which I plan to restore soon. It needs new shutter straps. I'll have to send it to Yuri in New York for that though..
I once adapted a I61 to a J8 shell. It took a bit of machining as well as trial and error to get the proper register but it worked great. Ended up selling it to a rangefinder forum member..
Most Yashicas I find nowdays has to have the POD replaced so I went over to the Kodak Retinas and Agfa Karats..Schneider optic are some of the best out there..
My Leicas are still my main users though..
