I picked up a very clean 1957 Zorki 4 for about $50 US including shipping from Ukraine. Came with a Jupiter 8 and is in beautiful condition. first test images were very sharp, and looked good even wide open. I also picked up a Canon 50mm f1.2 LTM to go with it. I went with the Zorki instead of the Leica III so I could spare some money for M30 optics. So far, I love the Zorki.
