Compact and capable, the Nikon Z 5 is an FX-format mirrorless camera with a well-rounded feature-set to suit both photo and video needs. Its 24.3MP CMOS sensor and EXPEED 6 processor afford wide sensitivity to ISO 51200, quick shooting at 4.5 fps, and UHD 4K video at 30 fps. Covering a useful range of focal lengths, the NIKKOR Z 24-70mm f/4 S is a versatile zoom, spanning wide-angle to portrait-length perspectives. Its constant f/4 maximum aperture maintains a consistent exposure throughout the zoom range and also helps to realize a more compact and lightweight alternative to an f/2.8 zoom. In regard to the optical design, a unique aspherical extra-low dispersion element, in addition to three aspherical elements, is used to help reduce chromatic aberrations and distortions throughout the zoom range in order to achieve high image sharpness and clarity. Both Nano Crystal and Super Integrated Coatings have also been applied to control flare and ghosting for greater contrast and color rendering in bright and backlit conditions.
