Thank you for viewing. [Good Condition] PENTAX Mount Adapter K - Tested and Working is for sale. I have confirmed that by attaching the adapter to a K-mount camera and mounting an M42 mount lens, infinity focus is achieved. The exterior has minor scratches from use. #okcamera_productlist #okcamera_Pentax I also have other cameras and lenses for sale. Please take a look if you'd like.
