Nikon 17-55mm f2.8G ED AF-S DX Nikkor format_APS-C black-paint lens made in 1946The Nikon 17 55mm f2. 8G ED AF S DX Nikkor is effectively a "24 70mm" pro lens for DX format cameras, with a useful wide to portrait range and a fast f2. 8 constant aperture. In good cosmetic condition, with some paint and finish wear; some internal dust. Focus and zoom action are good, diaphragm is clean. Not the most pristine 17 55mm lens you'll find, but it's got it where it counts.
