The Nikon NIKKOR Z 24-50mm f/4-6.3 is a compact standard zoom covering wide-angle to normal focal lengths. Its retractable design helps to achieve a slim form factor that is suitable to walk-around and travel shooting applications. A stepping motor provides quick, quiet, and precise autofocus performance along with a full-time manual focus override to suit both stills and video applications. Its optical design incorporates three aspherical elements and a pair of low-dispersion elements, which help to control a variety of aberrations for high sharpness and clarity. Standard zoom is designed for FX-format Nikon Z-mount mirrorless cameras but can also be used with DX models where it provides a 36-75mm equivalent focal length range. Two extra-low dispersion elements greatly reduce color fringing and chromatic aberrations throughout the zoom range in order to produce greater clarity and color rendering. The stepping motor delivers impressively smooth, quiet, and fast autofocus performance that is well-suited to both stills and video applications. A specialized electromagnetic aperture mechanism provides greater exposure control stability that is especially beneficial when working with fast continuous shooting rates.
