The M.Zuiko Digital ED 40–150mm 2.8 PRO is a professional telephoto zoom lens made by Olympus for the Micro Four Thirds system. It is the first telephoto lens in the Olympus M.Zuiko PRO range, which features weather-sealed, metal construction and high-performance optics intended to accompany the higher-end weather-sealed Olympus OM-D bodies such as the E-M1 Mark II. The lens features an integrated lens function button (configurable on the camera) and manual-focus clutch, and ships with a tripod collar and collapsible lens hood.
