This is the closest forum I could find on head-fi to sell this, I know it's not really the right place but I trust the community and know that there are quite a few photographers on here. I'm looking to eliminate some of my stuff and this lens hardly got used and just took up space. The lens itself is very highly regarded and performs wonderfully there are very very low cycles on it less than 50 probably. I purchased this brand new from B&H Photo just under 3 years ago, it has a B+W UV/Haze filter installed and has been on since I took the lens out of the box.
