The Nikon AF-S Nikkor 50mm f/1.4G Lens is a standard lens with an ultra-bright f/1.4 aperture, which allows for fast, accurate shooting with available light. It is also the excellent choice for when a shallow depth of field is desired. An ideal portrait lens when used on a Nikon DX-format digital SLR, it approximates the angle of view similar to that of a 75mm lens on a Nikon FX-format digital SLR or a 35mm film camera. The optical design of this lens minimizes flare and chromatic aberration. The SWM (Silent Wave Motor) feature ensures fast and quiet focusing action, and the nine-blade rounded diaphragm makes out-of-focus elements blend smoothly to produce natural-looking, harmonious backgrounds.
