Olympus M.Zuiko Digital 12-40mm f/2.8 Pro
The Olympus M.Zuiko Digital 12-40mm f/2.8 Pro is a new splash-, freeze- and dustproof standard zoom lens for Micro Four Thirds cameras. Covering a 35mm equivalent focal range of 24-80mm, the Olympus M.Zuiko Digital 12-40mm f/2.8 Pro lens offers a constant maximum aperture of f/2.8 throughout its zoom range. The optical formula comprises 14 elements arranged in 9 groups, including 1 aspherical element, 1 dual-sided aspherical element, 2 ED glass elements, 2 HR glass elements, 1 EDA glass element and 1 HD glass element. Other highlights include a manual focus clutch mechanism, a 62mm filter thread and a customisable L-Fn button which, by default, allows users to temporarily suspend continuous auto focus when something suddenly comes between the lens and your intended subject. Initially, the Olympus M.Zuiko Digital 12-40mm f/2.8 will be available in a bundle with the new Olympus OM-D E-M1 compact system camera for £1949.99. In the US, the lens will be sold separately for around $1,100.
