Hello again to the Forum! I got a real good response last time, so I have another question. Just bought a Jupiter 9 85mm to go with the Bessa R I have. No probs mounting the lens, focus fine and the lens looks in good repair. The markings for focusing are on the bottom, but the lens screws on fine right to where it stops. I can't seem to get to focus anywhere near infinity even with the lens set at infinity. JunK? Do I bother running some film this weekend? Bite the bullet and buy a Zenit 3m for it and my MIR 37mm? I did Google searches and all, and no real good answer except not one of them says they're INcompatible. Thanks for any help!
