The NIKKOR Z 24-120mm f/4 S, from Nikon, is a wide-angle to short-telephoto zoom covering an extremely useful range of focal lengths to benefit a variety of applications from landscape to portraiture. The constant f/4 maximum aperture offers consistent performance throughout the zoom range and the lens features an advanced optical design for high sharpness and clarity. Featuring a combination of three ED elements, one aspherical ED element, and three aspherical elements, both chromatic and spherical aberrations are effectively eliminated throughout the zoom range for notable sharpness and clarity. The  Multi-focus system incorporates two separate AF drive units, which are synchronized, to deliver especially fast and accurate focusing throughout the zoom range. This system uses stepping motors, which offer impressively smooth and quiet autofocus performance that is well-suited to both stills and video applications. Dedicated manual focus ring at the rear of the lens for tactile and precise control over the focus position. The assignable L.Fn button works in conjunction with camera-based Fn buttons to provide seamless points for quickly changing exposure settings and other functions.
