This Minolta MC Rokkor-X PF 50mm f/1.7 prime lens comes with its rear cap. It is for use with SR (MC/MD) mount cameras and adapters. There is very light haze inside of it and scuffs, scratches, and some finish loss on its exterior. There are a couple of dents in its filter ring that will prevent the use of a screw-on filter. Its focus and aperture adjustments are both smooth and its glass is free of any fungus or separation to its elements. There is no oil on its aperture blades.
