AF-S: Focusing is driven by a "Silent Wave" motor in the lens instead of the focus drive motor in the camera. AF-S lenses focus faster than standard AF-Nikkors and almost completely silently. AF-S lenses with a "II" designation weigh less and are generally smaller than their equivalent predecessors.
0mm wide-aperture standard lens with high-quality optics and Nikons exclusive Silent Wave Motor (SWM) for whisper-quiet operation. 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.
