Very nice, lightly used Contemporary version of the Sigma 150-600 zoom. Very clean glass, no marks on it except a small smudge on the lens hood. Bought it a few years ago for a trip to Yellowstone, it was great for that and got some very nice pictures. I havent used it since. Time to let it go. Includes both caps, case, and original box. $750 cash only, firm on price.
