UV date code. mint condition, no problems what so ever, and sharp. comes with warranty card, box, bag, caps, and hood. just got a 16-35 2.8, and just need to get rid of this. 575 shipped. NO paypal, they have a chargeback on going right now saying the buyer asked for money back whe they didnt, its to much of a hassle to go back and forth with paypal right now. So MO or cashiers check by mail please.
