This is a standard zoom lens for Nikon F-mount digital SLR cameras. It covers 24-70mm with a constant maximum aperture of f/2.8. On a DX-format camera, the focal length is equivalent to 36-105mm in FX format. The lens has a VR (vibration reduction) mechanism with a 4.0-stop image stabilization effect, measured in NORMAL mode at the most telephoto setting on a camera with a 35mm-equivalent sensor, per CIPA standards.
The optical design uses ED lenses, aspherical lenses and high refractive index lenses to correct chromatic and other aberrations. It includes Nikon's first ED aspherical lens, which combines ED glass with an aspheric surface in a single element. Nano Crystal Coating reduces ghosting and flare in backlit conditions. Resolving power is higher than that of the AF-S NIKKOR 24-70mm f/2.8G ED.
Zooming is done with a rotating zoom ring. Focusing uses Nikon's internal focusing (IF) method with an ultrasonic autofocus motor, and manual focusing is available. The nine-blade circular aperture gives soft bokeh. The lens is built to hold up in hard usage environments.
