Normal-length prime lens is designed for DX-format Nikon F-mount cameras and provides a 52.5mm equivalent focal length.
Bright f/1.8 maximum aperture is well-suited to working in low-light conditions and also affords increased control over depth of field for working with selective focus techniques.
One aspherical element is used to reduce spherical aberrations and distortion in order to realize sharp imagery with accurate rendering.
A Super Integrated Coating has been applied to individual elements to suppress internal reflections, flare, and ghosting for improved contrast and color accuracy when working in strong lighting conditions.
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.
Rounded seven-blade diaphragm promotes a pleasing out of focus quality that benefits the use of shallow depth of field and selective focus techniques.
