Covering a useful range of focal lengths, the NIKKOR Z 24-70mm f/4 S is a versatile zoom, spanning wide-angle to portrait-length perspectives. Its constant f/4 maximum aperture maintains a consistent exposure throughout the zoom range and also helps to realize a more compact and lightweight alternative to an f/2.8 zoom. In regard to the optical design, a unique aspherical extra-low dispersion element, in addition to three aspherical elements, is used to help reduce chromatic aberrations and distortions throughout the zoom range in order to achieve high image sharpness and clarity. Both Nano Crystal and Super Integrated Coatings have also been applied to control flare and ghosting for greater contrast and colour rendering in bright and backlit conditions. Complementing the optics, a stepping motor provides quick, quiet, and precise autofocus performance along with full-time manual focus override to suit both stills and video applications. A programmable control ring can be set for intuitive adjustment over a variety of camera and exposure settings. Additionally, the lens has a button-less retractable barrel to realize a more compact form factor when not in use. {Key Features} - Z-Mount Lens/FX Format - Aperture Range: f/4 to f/22 - Aspherical Extra-Low Dispersion Elemen - Three Aspherical Elements {Box Contents} - Nikon NIKKOR Z 24-70mm f/4 S Lens - LC-72B 72mm Snap-On Front Lens Cap - Nikon LF-N1 Rear Lens Cap - HB-85 Lens Hood - Nikon CL-C1 Lens Case
