Nikon Z 24-50mm f/4-6.3 – Ultra-Compact Standard Zoom Lens. The Nikon NIKKOR Z 24-50mm f/4-6.3 is an extremely small, handy, and lightweight standard zoom lens for Nikon Z-mount cameras, offering versatility with a focal length range of 24-50mm (36-75mm in DX format). Weighing only 195g and measuring just 51mm in length (retracted), it is the lightest full-frame zoom lens in its class – ideal for travel, street photography, or portraits. The lens consists of 11 elements in 10 groups, including 2 ED glass elements and 3 aspherical lenses, and delivers very good image quality with high sharpness and low distortion despite its variable aperture of f/4 to f/6.3. The quiet stepping motor (STM) ensures fast, precise autofocus, perfect for video, with a minimum focusing distance of 35 cm and a maximum magnification of 0.17x. The lens is dust- and splash-proof, has a 52 mm filter thread, and a 7-blade aperture (f/4 to f/36). Its retractable design makes it exceptionally portable while still delivering the image quality of a Nikon Z lens.
