I am selling a lightly used 17-40 f/4L simply because it doesn't get much use and I need it to fund other equipment. This lens is very sharp and in superb condition. It looks like it just came from the store. original box, bag, lens hood are all included. The lens also comes with a B+W UV filter which has been attached since day 1. I am asking $600 shipped paypal gift. I have very positive feedback on ebay using the same user name. Thanks!
