The AF-S NIKKOR 50mm f/1.4G lens is a fast, fixed focal-length lens with normal picture angle when used with Nikon’s FX-format D-SLR cameras. Its newly developed optical system delivers high performance, efficiently correcting sagittal coma flare and chromatic aberration. It features a large maximum aperture of f/1.4 that ensures a bright viewfinder image, and is ideal for low-light shooting situations or when a shallow depth of field is desired. The SWM ring type also offers smooth and quiet AF operation. Whilst all lens groups shift during focusing, the front element and filter mount does not rotate and the barrel length does not change, which makes it an ideal lens for close-up photography or when using SB-R200 Wireless Remote Speedlight units. The AF-S NIKKOR 50mm f/1.4G has two focus modes, M/A (manual-priority autofocus) and M (manual focus). With its rounded nine-blade diaphragm, out-of-focus elements appear more natural. When mounted on a DX-format SLR, the picture angle is equivalent to a focal length of about 75mm in 35mm format.
