Our new M.Zuiko Digital ED 12-45mm F4.0 PRO is the world’s smallest, lightest medium range zoom lens with a fixed aperture value*. It fits right in with our OM-D line — known as the world’s most portable camera system. Like OM-D cameras, the lens is weathersealed so you can work in adverse conditions without protective gear. Achieve high-resolution edge-to-edge sharpness at all focal lengths and high-speed focusing that works with our blazing-fast autofocus system. It goes anywhere and shoots a little of everything from landscapes and cityscapes to portrait shots.
