50mm FX-format standard lens (75mm when used with a Nikon DX-format SLR). Fast maximum aperture of f/1.8. Ideal for low-light situations or portraits with smooth bokeh. Aspherical lens element for superior image quality. SWM (Silent Wave Motor) for fast quiet autofocus. Two focus modes: M/A (manual-priority autofocus) and M (manual focus). Remarkably lightweight and compact body. Weather-sealed metal lens mount. Outstanding value for money.
