Another vote for the FSU lenses. For that matter, a vote for the FSU cameras. I shoot both a Fed 2, and two Zorkis (a 4, and a 4K). I love the cameras, and I love the glass. I have a couple og Jupiter, and a couple of Industars. Both quite sharp, and contrasty. I was also lucky enough to find the Orion 15 28mm for a pretty decent price. It is a bit slow at f 6, but Ihave gotten some stellar results with this very rare lens. I recently found 2 of them on "the bay", and I wish I had the extra $$ to invest in them.
