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.
