Up for sale is my Sigma 14mm f/2.8 EX lens in Canon mount. I bought it from KEH in EX condition last year for $670. It's now in EX- or G condition. There's a camera-bag rub on the side that has worn off some of the barrel finish. Obviously this has nothing to do with image quality, but if you want a mint lens this isn't it. Zero scratches on the glass, both sides.
The lens is great, but I use it only for exaggerated streched-dog photos once per shoot and thus am moving to a fisheye. It comes with the Sigma front cap/ring as well as the original green Sigma lens case. Price is $550 shipped. I prefer Google Checkout, with which I can send you a simple online invoice. If you're in Colorado I have to charge sales tax because this was business gear. But you're probably not.
