FS: Sigma 120-400mm F4.5-5.6 APO DG OS for Canon Mount

[Cory]

Sigma 120-400mm F4.5-5.6 APO DG OS for Canon Mount

Open box. Only used three times off my own back deck.
Like-new, stored indoors in a Pelican hard case.
Selling due to replacement with a superior Canon L Lens.

Lens is in perfect shape. As you can see from the picture everything that came in the box is there and in like-new condition.
Pictured with Tamron lens cap (I replace all my caps with these as I like them better than the Sigma or Canon ones).

$500 + Shipping / I'll be posting it up on Amazon/CraigsList soon if no one here is interested.
