This is a converted lens from a Yashica Electro 35, adapted to a Sony E-mount. I purchased it on a flea market app last year. The exterior shows some wear and tear consistent with its age, but the lens itself has no mold or noticeable scratches. The focus ring is smooth, but the aperture ring is a bit stiff. The image quality is surprisingly good for a lens from a camera made 60 years ago, and I loved using it for snapshots. I've attached some sample photos. I'm selling it because I sold my E-mount camera. Yashica Yashinon-DX 45mm f/1.7 Old lens SONY Single-focus lens
