Nikon AF-S Nikkor 17-35mm f/2.8D ED-IF

The Nikon AF-S Nikkor 17-35mm f/2.8D ED-IF is a relatively old lens, and was for a while the only practical fast standard zoom on Nikon's early professional DX (APS-C) format bodies. On full-frame bodies it's a useful ultra-wide angle zoom, and offers very good central sharpness at all apertures, improving upon stopping down. Edges are rough though, and don't really ever sharpen up, and heavy vignetting is impossible to ignore between F2.8-4. At this point in time, the 17-35mm F2.8 stands as a solid, no-nonsense lens that will take a lot of abuse, but optically it has been roundly surpassed by the AF-S Nikkor 14-24mm f/2.8G ED and the more practical, but slower AF-S Nikkor 16-35mm f/4G ED VR.
