SIGMA 17-50mm F2.8 EX DC HSM Pentax K-mount Focal Length (Wide)...17mm Focal Length (Tele)...50mm Maximum Aperture...2.8 Accessories other than the lens body include: hood, front cap, rear cap, soft case, original box (all genuine) and a protective filter (inexpensive). Purchased new several years ago, I had the focus adjusted at a Pentax service center immediately after. I then had the lens body's focus adjusted by Sigma, and mounted it on my K-5 body. However, I only used it a few times before I stopped using it. It has been stored in a dehumidified storage box and is, of course, in working condition. There are no noticeable scratches, and I can't see any dust or mold. I think it's in very good condition.
