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. Both Nano Crystal and Super Integrated Coatings have also been applied to control flare and ghosting for greater contrast and color rendering in bright and backlit conditions. 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. Constant f/4 maximum aperture affords consistent performance throughout the zoom range and also contributes to the relatively lightweight design and compact form factor. A Nano Crystal Coat, along with a Super Integrated Coating, has been applied to lens elements to minimize surface and internal reflections for a marked reduction in lens flare and ghosting. Full-time manual focus override is also possible and an internal focusing design is used, where only the internal lens groups are moved during focusing, to maintain the overall length of the lens during use and to promote faster-focusing speeds. A specialized electromagnetic aperture mechanism provides greater exposure control stability that is especially beneficial when working with fast continuous shooting rates. Exposed elements feature a fluorine coating that affords protection to the optical system against dust, grease, and water droplets.
