The AF-S Zoom-NIKKOR 17-35mm f/2.8D IF-ED is a wide-angle zoom lens for Nikon F-mount cameras. It is designed for FX-format sensors. On DX models it gives a 25.5-52.5mm equivalent focal length range. It keeps a constant f/2.8 maximum aperture throughout the zoom range.
The optical design uses three aspherical elements and two extra-low dispersion (ED) elements. The aspherical elements reduce spherical aberrations and distortion. The ED elements reduce color fringing and chromatic aberrations. A Super Integrated Coating on individual elements suppresses internal reflections, flare and ghosting, which helps contrast and color accuracy in strong or backlit light.
A Silent Wave Motor drives the autofocus quickly and quietly, with full-time manual focus override. The internal focusing design moves only the internal lens groups, so the lens length stays the same during focusing. A rounded nine-blade diaphragm gives a pleasing out-of-focus quality for shallow depth of field and selective focus.
