I bought a 20mm 2.8 from my local shop and it's been in my case and hasn't gotten to come out to play except for a handful of times. I bought it for $500, but will sell for $425. Here is the e-bay link. The lens is virtually BRAND NEW! I have unfilled USA warranty card, original box, packing materials, papers, etc. The lens is pristine, and there are no problems. It was only purchased several months ago. here is my e-bay link, or you can make me an offer i can't refuse and i'll end the listing. Canon EF 20mm f/2.8 USM Lens - eBay (item 130396095799 end time Jun-01-10 12:54:59 PDT) Good luck and thanks for looking!
