For excellent portraits in low light, the AF-S Nikkor 85mm f/1.4G lens provides outstanding optical performance in a professional F-mount telephoto prime, with bokeh from a 9-blade rounded aperture. This professional medium telephoto lens features a fast f/1.4 aperture, as well as a Silent Wave Motor (SWM), and Nikon's Nano Crystal Coat to reduce ghosting and flare. The 9-blade rounded aperture produces soft and pleasing blur characteristics. It is designed for use with Nikon's FX-format DSLRs.
