The Canon FD 300mm f5.6 S.C. lens is a good quality telephoto lens for the Canon FD mount. This lens is in very good cosmetic condition overall, with minor paint and finish wear, except for two small sections of the front lens ring, where the word “Canon” has been ground away. I don’t know why… maybe it’s the Canon equivalent over putting tape over the red dot. Either was, no effect on function. There is minor dust in the optics; focusing and diaphragm action are good. Includes tripod mount.
