A lens that corresponds to a 70-200mm in full frame for the Micro Four Thirds system. The f/2.8 aperture at all focal lengths makes it easier to work in various lighting conditions and provides impressive background blur for portraits, for example. Two ED and UED elements, along with a nanoparticle coating, reduce chromatic aberrations and internal reflections. In addition to its advanced optical structure, the lens features Power OIS image stabilization, which is compatible with Dual IS, as well as fast autofocus. Furthermore, the lens is splash and dust resistant and can withstand cold weather. This lens is truly a versatile tool for any situation.
