I Have searched, and I must admit that the workings of this forum are a mystery to me, but I need advice. I have a number of lenses that are compatible with the Ricoh xrp, which I liked very much. My question: has anyone had experience with using the ricoh lenses on the Pentax K10D. If so how does it work out. Focus, to infinity? exposure, How does that work. Please help, I don't want to abandon my Ricoh K mount lenses if I don't have to. PS: I am aware that the pin must be removed from the lenses. Thanks in advance
