Nikon 50mm f/1.8G Auto Focus-S NIKKOR FX Lens for Nikon Digital SLR Cameras The AF-S NIKKOR 50mm f/1.8G Lens from Nikon is an attractive alternative to the classic 50mm f/1.4 "normal" lens for everyday shooting with an FX or 35mm camera. The 50mm f/1.8 is nearly as "fast" as the f/1.4 and provides reduced lens flare and ghosting as well as superior color consistency through the use of Nikon's Super Integrated Lens Coating. One aspherical lens element virtually eliminates coma and spherical aberration. Nikon's Silent Wave Motor gives you smooth, silent and precise autofocus operation, and the M/A mode lets you quickly and easily override the autofocus system for fine manual focusing. This lens is also compatible with DX cameras and when used with a DX camera, the angle of view would be equivalent to a 75mm focal length lens.
