Canon Rare FL-F 300mm f5.6 Fluorite Telephoto Prime Lens w/ Case -Read-
This is the FL-F 300mm f5.6, the first lens to use fluorite to correct chromatic aberration. It is in excellent lens with high quality optics and interesting history.
This one is in good condition with moderate wear. There is a very small mark behind the front element but I can only see it with a flashlight and it is on the edge of the glass, it won't affect your image quality, especially on a lens this long. Otherwise the glass is clean with no haze or fungus. The focus is smooth and the aperture is dry and snappy.
The leather case is included, it has a few MTV stickers on it but works perfectly.
