I picked up a Minolta Rokkor-x 45mm f2 for ~$20 bucks shipped, and the focus ring seems to be broken somehow. There's ~10 degrees play in it before it catches and actually starts physically moving the lens element to focus. This play exists in the direction that I'm turning the focus. It happens in both directions It doesn't seem to affect the close end of the focus, as I can focus to ~2 feet. I cannot, however, focus to infinity, and I'm limited at about ~8 feet. The ring catches at 8 feet on the focus scale when rotating back to the left from infinity, thereby focusing closer (I hope this makes sense). I already contacted the seller to see what they'll suggest. I'm not too terribly pissed since I didn't pay much; but still, the lens was misrepresented. Anyway, I'm tempted to open this puppy up. Anyone ever come across something like this?
