Spanning an impressive wide-angle range, the NIKKOR Z 14-30mm f/4 S 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.
