Sigma 50 MM F 1.4 EX DG HSM for Nikon is designed for use with full frame digital cameras. It can also be used with smaller APS-C size sensors with a corresponding effective increase in focal length to about 75mm with most cameras. In the past few years, camera manufacturers have overlooked the need for a reasonable fast prime lens that is compact enough for everyday use, yet provides the necessary image quality to meet the highest expectations. Now, with the advent of the APS-C cameras, the long popular 50mm focal length takes on double duty as a portrait length lens of approximately 75mm on most of the small chip cameras. The lens is designed with molded glass aspherical lens elements for superior corrections of chromatic aberration & high image quality at all working distances. The Hyper-Sonic Motor ensures a quiet and high-speed auto focus. 9-blade diaphragm creates a pleasant out-of-focus-effect on backgrounds.
