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 [135] 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.
