The AF-S NIKKOR 28mm f/1.4E ED from Nikon is a flexible lens designed for FX-format F-mount DSLRs. Pairing with the comfortable focal length is the bright f/1.4 maximum aperture, which benefits working in low-light conditions and also offers increased control over the depth of field. Additionally, three aspherical elements are used to control spherical aberrations and distortion for high sharpness and accurate rendering. A rear focusing system also helps maintain the overall lens length during use by solely moving the rear lens group during use for faster performance. An electromagnetic diaphragm is also featured for greater exposure control stability which is especially beneficial when working with faster continuous shooting rates. Notably fast f/1.4 maximum aperture benefits working in difficult lighting conditions and also affords increased control over depth of field. Three aspherical elements are featured to control spherical aberrations and distortion in order to produce notable sharpness and resolution. Silent Wave Motor affords quick, quiet, and precise autofocus performance along with full-time manual focus override. A rear focusing design is also used, where only the rear lens group is 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.
