This is a standard zoom lens for Nikon F-mount DX-format cameras. It covers wide-angle to portrait-length focal lengths, equal to 25.5-82.5mm in 35mm terms. The maximum aperture is a constant f/2.8, so the light stays consistent across the zoom range. It also gives more control over depth of field for selective focus.
The optical design uses three aspherical elements and three extra-low dispersion (ED) elements. The aspherical elements reduce spherical aberration and distortion. The ED elements reduce color fringing and chromatic aberration. Super Integrated Coating on individual elements suppresses internal reflections, flare and ghosting in strong light.
A Silent Wave Motor provides quick, quiet and precise autofocus, with full-time manual focus override. The internal focusing design moves only the internal lens groups, so the lens keeps its length during focusing. A rounded nine-blade diaphragm gives a pleasing out-of-focus quality.
