This is a very nice Minolta Maxxum 50mm f1.7 AF lens (# 20201273) in excellent condition. The lens optics are clean with no haze, marks, fungus or dust visible when examined with strong back-light. The aperture blades are oil free and snappy. There are slight signs of use on the exterior, but no scratches or dings. The slide out lens hood works fine. The lens worked fine on a Konica Minolta 7D and a Sony Alpha 100. Generic front and rear caps, and a UV filter are included. This lens will also work on other Sony Alpha A AF digital cameras.
