Developed exclusively for use with Nikon DX Format digital SLR cameras, this lightweight, compact zoom lens is an excellent match for the new Nikon D2H digital SLR camera. The 17-55mm range exceeds 3x zoom to broaden wide angle to medium telephoto photographic possibilities, and the lens maintains fast f/2.8 aperture throughout to make it practical and easy to use. When mounted on any of the Nikon D2H, D1-series or D100 digital SLR cameras, the picture angle is the equivalent to 25.5 to 82.5mm on a 35mm  format camera. The range and image quality makes this the lens professionals and advanced enthusiasts will use most with Nikon DX Format digital SLR cameras for shooting portraits and close-ups, as well as nature studies. It also complements the AF-S DX Zoom-Nikkor 12-24mm f/4G IF-ED lens in Nikon s expanding DX Nikkor lens lineup. Nikon established yet stricter evaluation standards for the new lens, and it achieves greater picture resolution as a result. The newly developed optical system employed includes three ED (Extra-low Dispersion) glass elements that minimize chromatic aberration and three aspherical lenses that minimize distortion. Nikon s exclusive Silent Wave Motor (SWM) ensures fast, quiet autofocus. And the nine-blade rounded diaphragm opening provides a rich, natural look to out-of-focus elements. With its useful wide range and high quality performance, this compact, lightweight lens will help win a warm place for the Nikon DX format in the hearts of Digital SLR users.
