I'm selling my 100-400 IS that I purchased 2 years ago when I travelled to Africa for Safari. It has been a fantastic lens, and I've gotten some great shots (for me, at least) with it. : )
I hate to see it go, but I rarely use it now, and we are expecting our first child in September. I'm going to be putting the funds into some glass that's more appropriate for indoor, lower light photos.
The lens is in mint condition, and includes everything that came in the original box. Lens, hood, both caps, tri-pod mount, lens case w/strap, instructions, blank warranty card. The original box has the UPC code removed, as there was a rebate at the time.
There are a couple of tiny scratches on the bottom of the lens hood, which came from normal use. Does not affect usage in any way, and you probably wouldnt even notice. The lens itself, barrel and glass, are clean.
Here is a link to a quick album I put online of some wide open shots at 400mm that I took tonight, as well as some shots from Africa.
