The AF-S DX NIKKOR 10-24mm f/3.5-4.5G ED Lens from Nikon is wide-angle zoom lens designed for the DX (APS-C) format sensor found on many Nikon DSLRs, but can also be used on certain full-frame models utilizing their crop-sensor mode. As it stands, this lens will project an angle of view equivalent to a 15-36mm lens in the FX or full frame format. The primary user of a lens such as the 10-24mm Zoom-Nikkor will be one who finds standard kit lenses not quite wide enough for their tastes when photographing landscapes or interior views. An added benefit of wide angle optics is their ability to focus extremely close for a unique perspective on macro objects as close as 9.5" (24cm). This ultra-wide angle lens incorporates some of the best of Nikon's technical accomplishments in optical engineering. This 10-24mm lens features two extra-low dispersion (ED) lenses and three aspherical lens elements to reduce chromatic and spherical aberrations. Nikon coats their glass with their own Super Integrated Coating that makes light transmission more efficient, virtually eliminating ghosting and flare. Focusing is facilitated by a speedy and quiet Silent Wave Motor augmented by an internal focusing design that eliminates changes in barrel protrusion. Full time manual focusing override is available with the M/A focusing
