The Samyang AF 85mm f/1.4 F is a Nikon F-mount lens well-suited for portraiture. Its bright f/1.4 maximum aperture enables extensive control over the depth of field for using selective focus, and it also excels in low-light conditions. The optical design features a hybrid aspherical element, which controls distortion and spherical aberrations in order to produce greater sharpness and clarity throughout the aperture range. Individual elements also sport an Ultra Multi-Coating to suppress flare and ghosting for improved contrast in various lighting conditions. Benefitting the optics, the lens also features an Ultrasonic Dual Linear autofocus motor for quick and accurate focusing performance.  The portrait-length prime is designed for FX-format Nikon F-mount cameras, however, can also be used on DX models where it provides a 127.5mm equivalent focal length. One hybrid aspherical element is used to reduce distortion and spherical aberrations for greater sharpness and accurate rendering. Ultrasonic Dual Linear motor delivers quick, quiet autofocus performance. An AF/MF switch is also featured for seamless switching between focusing modes. The rounded nine-blade diaphragm contributes to a smooth and pleasing bokeh quality.
