Hi all,

I picked up one of these used lenses from a pawn shop and noticed that the barrel is very loose. I think the correct terminology is "creep"; but it's so bad that I would not be able to take a picture in any way except horizontal.

Is there any chance that this could be tightened to prevent the creep when it's not horizontal?

Also, I noticed that that even though it came with M42 mounth, this is actually and adapter (from what I've read these lenses can basically be put on many camera mounts); is there any documentation on how this adapter should be mounted on the lens properly to keep the right distance for my camera?

Thanks in advance!!
