Today I dug out a Ricoh pin equipped Tamron 28-210 PK/AR Auto lens (not autofocus) and in five minutes time (thanks to help from a forum member) removed the evil Ricoh pin. It was easy. I took out four little cross point screws from the back ring , bent up a plate, removed the Ricoh pin, saved it for whatever reason) and reattached the back ring exactly as it was, and done.
Now, for only $25, I have a lens I must autofocus, but this lens communicates with my K-x and I can shoot Manual, and Aperture priority and Speed Priority and even Program if I set the lens to A.
I’ll need to clean this lens on the inside when I get a kit to work on lenses, but it’s not too shabby as found.
I found I need to add about .7 EV to get exposure right. No need to green button meter. Point, focus, and shoot.
