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. Note: This lens is not compatible with 35mm [135] format or IX240 format film cameras This new DX Nikkor lens' true focal length is 17-55mm with a picture angle that will vary from 79° at 17mm to 28°50' at 55mm. The combination of reduced picture angle and a smaller image circle enabled the creation of this compact, lightweight DX Nikkor lens that covers a range from wide-angle to portrait and medium telephoto shots.

* The world's first constant f/2.8 3.2x zoom lens developed exclusively for use with Nikon DX Format * 3.2x zoom covers from a wide angle of 79° to a narrow angle of 28° 50' (equivalent to 25.5mm to 85.5mm for 35mm format) and is ideal for architecture, landscape, groups shots and portraits. * DX design enables a combination of wider angle-of-view with optical characteristics that are optimized for Nikon digital SLR camera sensors * Nikon DX design produces a smaller image circle (the size of the image that is projected by the lens on to the sensor) enabling smaller lens diameter, lighter weight and optimal image quality from center-to edge-to-corner on the image * 3 Extra-Low Dispersion (ED) glass elements for minimized chromatic aberration and provide higher resolution and superior contrast * 3 Aspherical lens elements for minimized distortion * Lightweight and compact design: similar to 17-35mm f/2.8 lens * Exclusive Silent Wave Motor enables ultra-high-speed autofocusing with exceptional accuracy and powerful super-quiet operation * M/A] and [M] modes allow rapid switching between AF and MF operation * Internal Focusing (IF) design for smoother focusing and great body balance * Nikon D-type design provides precise distance information for flash and ambient light exposure processes * Rounded diaphragm to make out-of-focus elements appear more natural * G Type DX Nikkor is designed exclusively for use with Nikon Digital SLR models * Fully Compatible with D1, D1X, D1H, D2H and D100
