I'm looking for an real, genuine, not-a-copy Pentax lens adapter permitting me to put my M42 screw mount lenses on a K body (an MX, specifically). I know there are many others made by some good and some not-so-good companies, but I think it's safest to use the real deal. (I wonder if they came with, or require, a removal tool?) Please PM me if you have one for sale -- I'd appreciate it.
