The Nikon NIKKOR Z 40mm f/2 is a versatile prime straddling wide-angle and normal fields of view and featuring a bright f/2 maximum aperture. The distinct focal length is wide enough for spontaneous shooting but still tight enough for portraiture and selective focus shooting. In terms of handling, a stepping motor AF system offers quiet and smooth focusing performance that benefits both stills and video capture and a programmable control ring can also be set for intuitive adjustment over a variety of camera and exposure settings. Bright f/2 maximum aperture excels in difficult lighting conditions and also offers increased control over depth of field for isolating subjects using depth of field. Super Integrated Coating suppresses flare and ghosting for improved contrast and color fidelity when working in strong lighting conditions. Full-time manual focus override is also possible and an internal focusing design is used, where only the internal lens groups are moved during focusing, to maintain the overall length of the lens during use and to promote faster focusing speeds. The specialized electromagnetic aperture mechanism provides greater exposure control stability that is especially beneficial when working with fast continuous shooting rates.
