I'm selling my Canon 400mm f/4 DO lens. I originally had the 500mm but it was too heavy. This lens has seen little use as I never became interested in wildlife and do mostly landscape work with medium format gear. The lens is in excellent shape. This lens is extremely small and light when compared to Canon's other telephoto's and is very sharp. It's a great lens for sport and wildlife work.
Asking $4400, which includes shipping. U.S. only. Contact me by PM if you are interested.
