Nikon Z 24-70mm f4 | lens Nikkor Z 24-70mm f4 lens

Covering a useful range of focal lengths, the NIKKOR Z 24-70mm f/4 S is a versatile zoom that spans perspectives from wide-angle to portrait length. Its constant maximum aperture of f/4 maintains constant exposure throughout the zoom range and also helps to realize a more compact and lightweight alternative to an f/2.8 zoom. Regarding the optical design, a unique aspherical extra-spherical scattering element is used, in addition to three aspherical elements, to help reduce chromatic aberrations and distortions throughout the zoom range for high image sharpness and clarity. Both Nano Crystal and Super Integrated Coatings have also been applied to control flashes and ghosting for greater contrast and color reproduction in bright light and backlight conditions.

Complementing optics, a stepper motor provides fast, quiet, and accurate autofocus performance, along with full-time manual focus override to suit both still images and video applications. A programmable control ring can be configured for intuitive adjustment in a variety of camera and exposure settings. In addition, the lens has a retractable barrel without buttons for a more compact form factor when not in use.

• The standard zoom covers a range from wide-angle to portrait length and is designed for FX-format Z-mount mirrorless cameras.
• The constant maximum aperture of f/4 offers consistent performance throughout the zoom range and also contributes to the relatively lightweight design and compact form factor.
• An extra-low dispersion aspherical element is incorporated into the optical design, along with three additional aspherical elements, to greatly reduce chromatic and spherical aberrations, distortion, coma (aberration), and flare for uniform edge-to-edge sharpness and illumination. .
• A nanocrystal layer, along with a super-integrated layer, has been applied to the lens elements to minimize internal and surface reflections for a marked reduction in lens reflection and the appearance of ghosting.
• The stepper motor delivers impressively smooth, quiet and fast autofocus performance that is suitable for both still images and video applications. It is also possible to override full-time manual focus and an internal focus design is used, where only the internal lens clusters are moved during focusing, to maintain the overall length of the lens during use, and to promote faster focusing speeds.
• The programmable control ring is set by default to adjust manual focus, but can also be used to control aperture or exposure compensation.
• The specialized electromagnetic aperture mechanism provides greater exposure control stability which is especially beneficial when working with fast continuous firing speeds.
• The seven-leaf rounded diaphragm promotes a pleasant out-of-focus quality that benefits the use of shallow depth of field and selective focusing techniques.
• The exposed elements have a fluorine coating that provides protection to the optical system against dust, grease and water droplets.
• Dust and moisture resistant lens barrel benefits the use of the lens in inclement conditions.
• The retractable buttonless design maintains a compact form factor when the lens is not in use.
