Two months after issuing a development notice, Olympus today officially announced the M.Zuiko Digital 17mm f/1.8 lens. Designed for street photographers, this new, fast moderate wide-angle lens for the Micro Four Thirds system features a maximum aperture of f/1.8 plus depth-of-field and distance indicators. These come into play when the lens is set to MF mode, enabling users to utilise the time-honoured technique of zone focusing, which is great news for street photographers. More than a full stop faster than the existing Olympus M.Zuiko Digital 17mm f/2.8 (read review), the new M.Zuiko Digital ED 17mm f/1.8 features the faster MSC (Movie & Stills Compatible) auto focus mechanism. The new M.Zuiko Digital 17mm f/1.8 lens will be available in December, at a price of £449.99/$499.99.
