Employing a re-designed optical system that includes Nikon’s exclusive Silent Wave Motor (SWM) and Nano Crystal Coat (N), the AF-S NIKKOR 85mm f/1.4G inherits its predecessor’s ultra-fast f/1.4 maximum aperture and rounded nine-blade diaphragm for superior depth-of-field control and background blur (bokeh). Engineered to inspire new levels of creativity and artistry, the AF-S NIKKOR 85mm f/1.4G will unleash the full potential of your Nikon D-SLR or HD-SLR—in the studio or in the field.
