Originally posted by reh321 I have enough adapters that I can 'assign' one to each M42 lens. I remove the spring that keeps the adapter locked into the mount, so the whole assembly {lens + adapter} comes off together. Essentially, the lens + adapter is "just another" K-mount lens.
I do the same with all of my M42 lenses. I even go so far as to place a small bit of Loctite 242 (removable) to keep the adapter on the lens.
M42 to PK adapters are cheap, so it makes sense to fit each lens an have a PK rear cap, which is consistent with all my regular bayonet lenses.
