Lens-making is an art--Nikon artisans craft Nikkor optics from the finest materials, taking pride in adding their intellect and technique to bring the world's finest lenses to life. They push the leading edge of lens-making in their effort to provide the "glass" that makes the world's greatest pictures.
AF Nikkor lenses work with Nikon SLRs for optimal performance, even the very latest. The 17-35mm f2.8D ED-IF AF-S Zoom Nikkor Lens is the standard lens for photojournalism and travel photography, perfect for use with a film or a digital SLR. It features a Silent Wave Motor, two types of aspherical lens (two molded-glass lenses and one hybrid), and two ED glass elements for higher optical performance, 11.02-inch closest focusing throughout the zoom range, M/A mode for quick switching between autofocus and manual focus operation, and nine-blade rounded diaphragm that achieves a natural blur for out-of-focus elements. The ED glass element reduces chromatic aberrations providing superior optical performance--even at maximum aperture. There is also no power drain when manually focusing.
