"Olympus has announced a weather-sealed 12-50mm F3.5-6.3 motor zoom lens with macro capabilities. The M.ZUIKO DIGITAL ED 12-50mm F3.5-6.3 EZ covers the 24-100mm equivalent range and is optimized for video capture. It offers multi-speed powered zooming with a manual zoom option. It also has an AF-hold button (marked as L-Fn) that suspends AF to avoid re-focusing on the wrong object. It is the first Micro Four Thirds lens to feature the same level of sealing as the company's high-end SHG lenses for Four Thirds DSLRs."
