The 28-75mm F/2.8 Di III VXD G2 (Model A063) is a fast-aperture standard zoom lens for Nikon Z-mount full-frame mirrorless cameras. The lens is the successor to the popular 28-75mm F/2.8 Di III RXD (Model A036), the lens that flipped conventional thinking about standard zoom lenses upside down. High definition and spectacular image quality are the key areas of advancements. The A063 features a redesigned optical system but maintains a size similar to its predecessor.
