Nikon NIKKOR Z 14-30mm f / 4 S lens
With an impressive wide-angle range, the NIKKOR Z 14-30mm f / 4 S is an ultra-wide-angle zoom for the Nikon FX-format Z-series mirrorless system. The wide field of view is especially suitable for landscape, architecture and astrophotography applications, and the constant maximum aperture of f / 4 maintains a constant exposure throughout the zoom range. With respect to the optical design, the lens features four elements of extra low dispersion and four aspherical elements, which reduce a variety of aberrations and distortions to produce images with high sharpness, clarity and precise color reproduction. Both Nano Crystal and Super Integrated Coatings are also used to suppress flashes and ghosts for greater color fidelity and greater contrast.
As a complement to the optics, a stepper motor provides fast, quiet and precise autofocus performance along with a full-time manual focus override to accommodate both still images and video applications. A programmable control ring can be set for intuitive adjustment in a variety of camera and exposure settings. In addition, the lens has a retractable body without buttons to obtain a more compact form factor when not in use.
The ultra wide-angle zoom covers a wide-angle range to portrait length and is designed for mirrorless cameras with Z-mount FX format.
The constant maximum aperture of f / 4 offers constant performance throughout the zoom range and also contributes to the relatively lightweight design and compact form factor.
Four aspherical elements are used to reduce spherical aberrations and distortion to obtain sharp images with accurate representation.
Four extra-low dispersion elements greatly reduce color stripes and chromatic aberrations to produce greater clarity and color reproduction.
A nanocrystalline layer, along with a super-integrated layer, has been applied to the lens elements to minimize surface and internal reflections for a marked reduction in lens flare and phantom effect.
The stepper motor offers impressively smooth, quiet and fast autofocus performance that is suitable for both video and still image applications. Full-time manual focus override is also possible and an internal focus design is used, where only the internal lens groups move during focusing, to maintain the overall length of the lens during use and promote more focus speeds. fast.
The programmable control ring is set by default to adjust the manual focus, but can also be used to control the aperture or exposure compensation.
The specialized electromagnetic aperture mechanism provides greater exposure control stability that is especially beneficial when working with fast continuous shooting speeds.
The rounded seven-blade diaphragm promotes a pleasant unfocused quality that benefits from the use of shallow depth of field techniques.
The exposed elements have a fluorine coating that provides protection to the optical system against dust, grease and water droplets.
The dust and moisture resistant lens body 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.
