SIGMA 17-70mm F2.8-4 DC MACRO OS HSM | Contemporary For Nikon F mount. Operation confirmed. The lens has visible mold, so it is considered junk. Includes hood, front cap, and rear cap. A bright, compact, and convenient lens that can also be used for macro photography. How about using it with a single-lens reflex camera, or with a mirrorless camera via an FTZ adapter? Size: Nikon F mount Focal length (wide): 13-18mm Focal length (telephoto): 51-70mm
