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 depth of field. The optical construction utilizes two extra low-dispersion glass elements to correct chromatic aberrations and color fringing for notable clarity and color fidelity, and Nano Crystal and Super Integrated Coatings have also been applied to suppress lens flare and ghosting for greater contrast when working in strong lighting conditions. Additionally, three aspherical elements are used to control spherical aberrations and distortion for high sharpness and accurate rendering.
Balancing the optical attributes, the lens is also characterized by a Silent Wave Motor that produces fast, smooth, and quiet autofocus capabilities, along with the ability to manually override focus at any time for more selective control. 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 that is especially beneficial when working with faster continuous shooting rates.
- Versatile wide-angle prime is designed for FX-format Nikon F-mount cameras, however can also be used on DX models where it provides a 42mm equivalent focal length.
- Notably fast f/1.4 maximum aperture benefits working in difficult lighting conditions and also affords increased control over depth of field.
- Two 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.
- Three aspherical elements are featured to control spherical aberrations and distortion in order to produce notable sharpness and resolution.
- 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. 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.
- Fluorine coating on front element affords protection to the optical system.
- Dust- and moisture-resistant lens barrel benefits the lens' use in inclement conditions.
- Specialized electromagnetic aperture mechanism provides greater exposure control stability that is especially beneficial when working with fast continuous shooting rates.
