Canon 500mm f/4 L IS USM Lens For Sale

This lens is in great condition. The Lens Coat has been on since I purchased the lens.  There are few wear marks from the thumb-screw around the ring where the lens hood attaches. There is a little yellowing on the plastic window on the Lens Coat that was there when I got the lens, and one small piece is taped to the side of the tripod foot ring so I didn't take it off for the photos. There is a crease on the side of the lens hood near the front. I don't know where it came from because I've never had the Lens Coat off, so it may or may not have been there when I got the lens. Other than those few cosmetic things all functions work on the lens. I have found that I need to micro-adjust my cameras to tweak the focus point. It has been a great lens. I'm only selling it because I don't need it anymore.
