The Nikon AF-S NIKKOR 50mm f/1.8G Special Edition Lens is a fast normal prime lens that is designed for use on both Nikon FX and DX DSLRs. Its lightweight and stylish design integrates enhanced knurling on the focus ring to add a functional and aesthetic element that complement refined manual focusing control. When working with autofocus, a Silent Wave Motor (SWM) AF system is quick, precise, smooth, and quiet, which benefits both still and movie shooting.
One aspherical element is incorporated into the optical design to help minimize chromatic aberrations while also contributing to high image sharpness and clarity. A seven-blade rounded diaphragm helps to render a pleasing out-of-focus quality when working with selective focus and shallow depth of field techniques, which is further benefitted by the bright f/1.8 maximum aperture.
