Selling my 800mm. It's in great shape and makes razor sharp images at all stops. Optically flawless except for one tiny pinhead-size spot in the front element's coating which doesn't affect anything. Just a few normal spots of wear and marking on the barrel. Focus is smooth and the aperture functions perfectly. No fungus, hazing, or significant dust. Comes with the trunk case with keys, front cover, filter inserts, rear cap, and strap.
