This listing is for a Canon FD 50mm f/1.4 S.S.C. Fast Manual Focus Lens - For Repair or Parts.  The lens is in very good cosmetic condition showing light normal wear.  The glass elements are clean and clear with no haze or fuzz.  I tried the lens on my Canon FT QL and the aperture does not respond (close down to the selected aperture) when I press the meter lever.  For this reason, the lens is offered AS IS for repair or parts.  thanks for your interest and email if you have any questions.
