Nikon AF-S 10-24mm f/3.5-4.5G ED DX Nikkor
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).
