MINOLTA MD 50mm f/1.4 lens. It's a Minolta MC/MD/SR mount, but I was using it on a Sony FE mount camera with an adapter. A KENKO Black Mist Protector is also included as a bonus. It's a filter that's almost unused and in very good condition. Although there's a little bit of wear and tear, the focus ring, aperture ring, and mount are in very good condition. There's no lettering wear. The optics are free of mold and fogging, and there's very little dust, so they're very clean. There's no oil on the aperture blades. Please feel free to ask if you have any questions. Size...α E mount Focal length...19-70mm Maximum aperture...~1.4 Other features...Old lens, with rear lens cap, with front lens cap
