A compact wide-angle prime with intuitive handling and an advanced optical design, the black M.Zuiko Digital ED 12mm f/2 from Olympus is a 24mm equivalent lens for Micro Four Thirds mirrorless cameras. The wide focal length pairs with the bright f/2 maximum aperture to benefit available light shooting as well as astrophotography applications. The lenss optical design makes use of one aspherical element, one DSA (Double Super Aspherical) element, and a Super HR (high refractive index) element to reduce spherical aberrations and control distortion for notable sharpness, and one extra-low dispersion element reduces color fringing for high clarity and color accuracy. Additionally, the lens is characterized by its Movie & Still Compatible autofocus system for quick and quiet performance, as well as a manual focus clutch and Snapshot Focus mode for intuitive control over focus position and depth of field.
