Ricoh lens pin?

I just won a 50mm 1.4 ricoh lens on evilbay. Does anyone have a picture of this pin that needs to be plucked out so it wont get stuck on my body? Anyone ever use this lens? Thanks.

I haven't used that lens, but I have used a Ricoh 28mm and a 2X macro teleconverter on a Pentax AF camera without it getting stuck. The pin was smaller than the electric contacts on a Pentax lens. I think the stuck lens problem is limited to second-rate third party lenses. Brands refers to as "miscellaneous". If it's not a program lens, it will be the same as a Pentax-M lens.

I can't show you the pin, but I can show you the end result. The image below is a Tokina 24mm. At about the 7 OClock position you can see a covered pin hole just to the left of a small phillips head screw. This is where the offending pin was. I just gently moved it inside the lens body and sealed it with a dab of epoxy, sanded smooth.
