The optical design incorporates one extra-low dispersion element to reduce color fringing throughout the zoom range, as well as to provide improved clarity and color accuracy. Telephoto zoom designed for Micro Four Thirds mirrorless cameras, this lens offers a 200-600mm equivalent focal length range. Linear autofocus motor delivers fast AF performance that is also precise, smooth, and near-silent to benefit both stills and video applications. POWER Optical Image Stabilizer minimizes the appearance of camera shake for sharper handheld shooting, and also supports the Dual I.S. function for increased stabilization performance. Rounded seven-blade diaphragm contributes to a smooth and pleasing bokeh quality. Additionally, the lens also sports a splash and dustproof construction for use in trying environmental conditions.
