Thank you for viewing. For sale is a rare RICOH RIKENON 50mm P F2 with sticker, a Japanese-made Summicron, manufactured by Tomioka Optical, with a K-mount manual lens. I purchased this about 10 years ago when I was enthusiastic about finding old lenses. It came out of my parents' dry storage, so I am selling it to declutter. There is some slight dirt on the lens and fine dust inside the lens, but I don't see any mold or fogging. I don't see any problems in the photos taken with it. Also, there are no problems with the basic operations. There are fine scratches on the exterior due to normal use. Since this is a used item, please refrain from purchasing if you are concerned about any of the above points. Excessive price negotiations and ignoring comments are unpleasant, so I may block users. Thank you for your consideration. RICOH RIKENON 50mm F2 P Brand: Ricoh
