The Ricoh Auto Rikenon 50mm f/1.7 is a highly regarded vintage, manual-focus prime lens known for its solid build, compact design, and excellent optical performance. It produces rich, natural colors and is an affordable way to achieve smooth bokeh and great low-light performance on both vintage and modern mirrorless cameras.  This lens is in extremely good condition with very minor signs of wear on the barrel.  The lens is clean and clear.  No scratches, cleaning marks.  No noticeable dust and no fungus or separation.  The focus ring is just a bit snug but has never been a problem. The exposure ring clicks nicely and the auto/manual switch works as it should.  A terrific M42 mount which is widely adaptable to many modern digital cameras.  This lens was used by this seller on Pentax and Sony equipment with not issues. Please message with questions.
