The Olympus M.Zuiko Digital ED 20mm f/1.4 PRO Lens is a 40mm equivalent wide-angle prime lens for Micro Four Thirds mirrorless cameras. The wide field of view is complemented by a fast f/1.4 maximum aperture for controlling depth of field and producing selective focus effects, and when working in difficult lighting conditions. This pocket-sized lens is easy to carry and balances high resolution with the ability to capture soft, feathered bokeh. This lens makes long days of shooting landscapes, nature, or travel photos seem effortless. Reliable IPX1-rated weather sealing makes it possible to shoot in any environmental conditions without worry. Two aspherical elements are used in the optical design to help reduce spherical aberrations in order to achieve a high degree of sharpness, and also help reduce the overall size and weight of the lens. The Movie & Still Compatible (MSC) autofocus system provides precise, fast, and quiet focus performance to suit both video and photo applications.
