Hi John,
In answer to your posting. I bought mine in September 2007 from B&H. I used it 3-4 times for horse competitions in the summer when I was not allowed to be in the ring with the competitors. The lens has not been used in the other seasons.
I have : the original box, the case, the lens shade, the leather lens hood, a RRS plate, a Lowenpro AW 600 and naturally the lens. I use the RRS plate for the Wimberly head. There is a small ΒΌ inch scratch on the barrel near the camera end of the lens and there are very few specks of dust behind the front protective glass element. The photos at 100% do not show up on the photos. I would rate it as Mint 9/10. If you wish, I could at cost send it to Canon Canada for cleaning before shipping and I will pay the cost of shipping it to Canon.
After consideration, I am asking 6600 $ plus the Paypal fees and shipping fees. I am offering it because I am planning to stop covering the horse competitions within a year.
Yes photos are available, if you contact me directly
