I love this lens. Love it, love it, love it. But I love my L lenses better and I need a 30-inch display before I go blind. Up for grabs is a true wide angle lens: 12-24mm F4.5-5.6 EX DG ASPHERICAL HSM for Canon EF mounts. Not a scratch - comes with box, all original owners manuals and a ballistic nylon padded case. $500.00 with shipping included. Goes for about $620.00 on most REPUTABLE sites like B and H. No trades, gold coins, beads or other barters. PayPal only to verified addresses. U.S. sales only. Duff Man and Eva 01 are two recent buyers of mine if you want references.
