The AF-S Fisheye NIKKOR 8-15mm f/3.5-4.5E ED from Nikon is a fisheye zoom designed for FX-format F-mount DSLRs. At the wide end of the zoom range, the lens produces a circular field of view, which gradually covers the entire full frame by the long end of the focal length range. Also, Nano Crystal and Super Integrated Coatings have been applied to suppress flare and ghosting for improved contrast in strong lighting conditions. An electromagnetic diaphragm is also featured for greater exposure control stability when working with faster continuous shooting rates. The circular fisheye design at the wide end of the zoom range transitions to full-frame coverage by the long end of the focal length range. Three extra-low dispersion glass elements are used in the optical construction to reduce a variety of chromatic aberrations and color fringing for a high degree of clarity and color neutrality. Nano Crystal and Super Integrated Coatings have been applied to lens elements to minimize surface and internal reflections for a marked reduction in lens flare and ghosting. Silent Wave Motor affords quick, quiet, and precise autofocus performance along with full-time manual focus override.
