High-quality CANON FD 50mm f/1.4 S.S.C. lens. This is a Canon FD mount. - Brand: CANON - Model Name: FD 50mm f/1.4 S.S.C. - Lens Type: Prime/Single Focal Length - Country of Manufacture: Japan - Focal Length: 50mm - Aperture: f/1.4 - f/16 The lens has very little dust and is in generally good condition. When a light is shone through it, some cloudiness is visible on the inside of the front element. I believe this will have almost no effect on the images. Thank you. Operation has been confirmed. Includes front and rear caps. Thank you. Thank you for looking.
