This lens has been gently used. It is among the most versatile wide-angle zooms I've ever owned. While there are some cosmetic flaws along the focusing ring, the lens was recently shipped to Canon Professional Services and has a completely flawless bill of health. I am selling it to make room for a new setup.
I'm now to Gear Offer, and I'm eager to negotiate a reasonable price for a good rating. Let me know if you are interested!
