Canon 100-400mm f/4.5-5.6L EF IS Lens, barely used

This is an extraordinary long telephoto lens with impeccable 'L' glass quality. I bought it in may of 2007 and have only used it a handful of times, which is why I can't justify keeping it. It was used as a back up for my 600mm. It's still in like new condition. Also comes with Ritz camera warranty and will transfer to your name when you purchase.
