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 lens's 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.
