Incorporates Nikon's second-generation Vibration Reduction system for an exceptionally steady image, even in low-light. Nano Crystal coat greatly reduces ghosting and flare and the 9-blade rounded diaphragm enables super-smooth bokeh. Boasts quiet, accurate autofocus and a weather-sealed magnesium body.
