The NIKKOR Z 24-70mm f/2.8 S from Nikon is a standard-length zoom covering a wide-angle to portrait-length range for Nikons FX-format Z-series mirrorless system. Its bright constant f/2.8 maximum aperture ensures consistent results throughout the zoom range and also benefits working in low light conditions while offering increased control over depth of field. The optical design uses four aspherical elements to reduce spherical aberrations and distortion, while two extra-low dispersion elements reduce colour fringing and chromatic aberrations. ARNEO, Nano Crystal and Super Integrated Coatings are also used to suppress flare and ghosting for sharp images with accurate colour. A multi-focus system uses two stepping motors to provide fast, quiet, and precise autofocus performance that is well-suited to both stills and video applications.
Full-time manual focus override is also available, and an internal focusing design maintains the overall lens length, benefitting focusing speeds. An electromagnetic aperture mechanism provides greater exposure control stability that is particularly useful when working with fast continuous shooting rates, and a rounded nine-blade diaphragm produces attractive out of focus areas. A programmable control ring is set to adjust manual focus by default, but can also be set to control aperture or exposure compensation. The lens barrel is both dust and moisture resistant and incorporates a top OLED information panel that can be used to quickly confirm aperture and focus settings, and an assignable L.Fn button permits making exposure and settings adjustments via the lens.
