Nikon AF-S DX 17-55mm f/2.8G Black

The Nikon AF-S DX Zoom-NIKKOR 17-55mm f/2.8G IF-ED is a 25.5-82.5mm-equivalent zoom characterized by its bright maximum aperture and sophisticated optical design. The optical design incorporates three aspherical elements and three extra-low dispersion elements, which help to greatly reduce spherical and chromatic aberrations throughout the zoom range. Complementing the optics, this lens also sports a Silent Wave Motor for fast and accurate autofocus along with full-time manual focus control. Bright constant f/2.8 maximum aperture affords consistent illumination throughout the zoom range and also affords greater control over depth of field for working with selective focus techniques. Three extra-low dispersion elements greatly reduce color fringing and chromatic aberrations in order to produce greater clarity and color accuracy. Silent Wave Motor affords quick, quiet, and precise autofocus performance along with full-time manual focus override. An internal focusing design is also used, where only the internal lens groups are moved during focusing, to maintain the overall length of the lens during use and to promote faster-focusing speeds.
