Fixed it redneck style, WD-40! When I bought it the focus knob was stuck at infinity. I thought about using it just at infinity, but I found a little movement in the knob so I started lubing it and working it. After a couple of days it loosened up real good. I took the view finder apart and cleaned it too. So, here's a couple sample shots with it (Ektar 100). I really like the sharpness of this lens. I think I've got a winner here. At f3.5, wide open: At the park, stopped down to f11: f5.6 close focus: I'm very pleased with my $25 purchase!
