Yashica Yashinon 50mm f1.4 DS-M M42 Screw Mount Prime Lens -Read-
This is a nice 50mm prime lens for m42 screw mount. It would be an excellent addition to a classic m42 kit or adapted to mirrorless. Some of my first lenses on my mirrorless camera we adapted m42 lenses.
This one is in good condition with moderate wear. There are a few very small cleaning marks on the rear element but I cannot see them without a flashlight, they won't affect your image quality. Otherwise the glass is clean with no haze or fungus and a moderate amount of dust inside. The focus and aperture are smooth.
