The Olympus M.Zuiko ED 12-40mm F/2.8 PRO II is a constant-aperture zoom lens for cameras with a Crop Frame sensor and a Micro Four Thirds (MFT) mount. Its 14 elements in 9 groups include ED, aspherical, and HR elements to reduce aberrations throughout the focal length range and maintain sharpness from the center to the edges of the image. The ZERO coating reduces reflections and ghosting, while the fluorine coating on the front element repels dust, water droplets, grease, and dirt.
The MSC autofocus system operates quickly, smoothly, and quietly for still photography and video. The lens features a manual focus clutch mechanism for instantly switching to manual focus, as well as an L-Fn button on the lens barrel that can be assigned camera functions. It supports Focus Stacking with a compatible camera and offers a maximum image magnification of 0.6x.
