The AF-S NIKKOR 105mm f/1.4E ED Lens from Nikon is an incredibly bright portrait-length lens designed for FX-format F-mount DSLRs. The f/1.4 maximum aperture benefits working in low-light conditions and also affords extensive control over focus for shallow depth-of-field imagery. Availing a range of unique possibilities for a telephoto lens, the combination of the 105mm focal length and fast maximum aperture greatly benefits portrait photographers as well as event shooters. An electromagnetic diaphragm is also featured for greater exposure control stability which is especially beneficial when working with faster continuous shooting rates. Awesomely fast f/1.4 maximum aperture enables precise control over depth of field when working with selective focus techniques, and also benefits working in low-light conditions. A Nano Crystal Coat has 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. An internal focusing design is also used, where only the internal lens groups are moved during focusing, to maintain the overall length of the lens during use and to promote faster focusing speeds. The specialized electromagnetic aperture mechanism provides greater exposure control stability that is especially beneficial when working with fast continuous shooting rates.
