The snow finally let up for a while here in Meeechigan today, so I thought I would take out a few cameras for a little excercise. The RB and Zorki 1 worked great, but the Zorki 5 had serious issues with the shutter. It was acting like it was on bulb setting. The aperture ring also was so stiff I couldn't turn it, but I think I can handle that okay. I do need help however figuring out how to make the shutter work properly in the cold. Any suggestions?
