Vintage Ricoh Rikenon P 1:2 50mm Pentax K (PK) Mount Prime Lens

This is a vintage Ricoh Rikenon P F2 50mm Prime Lens with a Pentax K (PK) mount. It can be adapated easily to Canon EOS, Sony, and most modern digital cameras except modern Pentax, unless you remove the Ricoh pin on the mount. It is in fine condition, with no scratches on the glass, fungus, mold or haze, and only some fine specks of dust. The aperture works great, and there is no oil on the aperture blades. The lens was tested, and the details are sharp. Photos shot with a Auto Mamiya Sekor, 50mm F1:2 lens PK mount adapted to an EOS APS-C camera.
