Hi, as far as I can remember, Ricoh released it's own kind of "KA"-mount for the XR-P. This mount wasn't compatible with Pentax' KA-mount. Sigma then claimed to have the only line of lenses compatible both for Ricoh and Pentax-A. I have two such manual focus lenses, the Sigma 18mm/f2.8 and the 75mm/f2.8~200mm/f3.5 (both ca. 1986) - but never had a Ricoh to test this. They called it "KPR"-mount. On my MZ-3 it works just fine. (But this won't help you, I'm afraid.) Greetinx, Thomas
