The Olympus M.Zuiko Digital ED 14-150mm f/4-5.6 II is an evolutionary upgrade to the first Olympus 14-150mm Micro Four Thirds lens, which was announced back in November 2009. The main improvement is the addition of weather sealing, along with ZERO (Zuiko Extra-low Reflection Optical) coating on the surface of the front element, plus various cosmetic changes. Apart from the new lens coating, the optical construction is similar, featuring 15 elements in 11 groups and an iris diaphragm with 7 rounded aperture blades. The new lens also boasts the manufacturer’s MSC (Movie & Stills Compatible) auto-focus system, which promises fast and nearly silent focusing on all compatible camera bodies. Like its forebear, the new M.Zuiko Digital ED 14-150mm f/4-5.6 II lens offers a 35mm equivalent focal range of 28-300mm, while measuring just 83.0×63.5mm. The addition of weather sealing and improved mechanical construction have resulted in a marginally higher weight of 285 grams. The Olympus M.Zuiko Digital ED 14-150mm f/4-5.6 II is currently available for £549.99 / $599.00 in the UK and the US, respectively.
