The M.Zuiko Digital ED 14-150mm f/4-5.6 II Lens from Olympus is an extremely versatile all-in-one zoom for Micro Four Thirds mirrorless cameras. Spanning a wide-angle to telephoto range, this all-in-one zoom is providing a 28-300mm equivalent focal length to suit photographing in nearly any situation. Despite its reach, the lens still remains compact for easy portability comes with two E-HR (Extra-High Refractive Index) elements, and one high refractive index element are used to reduce spherical aberrations and distortion throughout the zoom range for increased sharpness and resolution. An EDA (Extra-Low Dispersion Aspherical) element and one extra-low dispersion element are also used to reduce chromatic aberrations and color fringing for improved clarity and color accuracy.A ZERO (Zuiko Extra-low Reflection Optical) coating has been applied to individual elements to minimize lens flare and ghosting for improved contrast and color fidelity when working in strong lighting conditions. Additionally, this 14-150mm lens also sports a Movie & Still Compatible (MSC) AF system that is quick and quiet and has a weather-resistant construction to suit working in inclement weather conditions.
