$500 or BO but I'm not selling for much less. I upgraded to the 2.8 IS verson for my weddings, so I don't need this anymore. It's in new, perfect condition. I looked for scratches, knicks, anything at all, and couldn't find anything. I have the lens case, the original box, the instructions, everything. I accet Paypal only because it provides protection for both of us. I used this lens 6 or 7 times before I had to get the faster one, so you can rest assured you are basically buying a new lens, but for cheaper. I'm located in Minneapolis, and local pickup is always prefered. Please send me an eMail at firstname.lastname@example.org or call me at 952-239-9194 if you're interested.
