- Z-Mount Lens/FX Format
- Constant f/4 Maximum Aperture
- Four ED and Four Aspherical Elements
- Nano Crystal & Super Integrated Coatings
Spanning an impressive wide-angle range, the NIKON Z 14-30 F/4S LENS is an ultra-wide zoom for Nikon's FX-format Z-series mirrorless system. The broad field of view is especially well-suited to landscape, architectural, and astrophotography applications, and the constant f/4 maximum aperture maintains a consistent exposure throughout the zoom range. In regard to the optical design, the lens features four extra-low dispersion elements and four aspherical elements, which reduce a variety of aberrations and distortion to produce imagery with high sharpness, clarity, and accurate color rendering. Both Nano Crystal and Super Integrated Coatings are used, too, to suppress flare and ghosting for greater color fidelity and higher contrast.
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.
- Ultra-wide zoom covers a wide-angle to portrait-length range and is designed for FX-format Z-mount mirrorless cameras.
- Constant f/4 maximum aperture affords consistent 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 in order to realize sharp imagery with accurate rendering.
- Four extra-low dispersion elements greatly reduce color fringing and chromatic aberrations in order to produce greater clarity and color rendering.
- 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.
- Stepping motor delivers impressively smooth, quiet, and fast autofocus performance that is well-suited to both stills and video applications. 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.
- Programmable Control Ring is, by default, set to adjust manual focus but can also be used to control aperture or exposure compensation.
- Specialized electromagnetic aperture mechanism provides greater exposure control stability that is especially beneficial when working with fast continuous shooting rates.
- Rounded seven-blade diaphragm promotes a pleasing out of focus quality that benefits the use of shallow depth of field techniques.
- Exposed elements feature a fluorine coating that affords protection to the optical system against dust, grease, and water droplets.
- Dust- and moisture-resistant lens barrel benefits the lens' use in inclement conditions.
