The Panasonic Lumix G Vario 100-300mm f/4-5.6 II POWER O.I.S. Lens spans an equivalent 200-600mm range, making it well-suited to wildlife, nature, and sports shooting. 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. Benefitting the optics, the lens also houses a quick, quiet, and precise linear autofocus motor as well as a POWER Optical Image Stabilizer, which supports the Dual I.S. function in select Lumix cameras. Additionally, the lens also sports a splash and dustproof construction for use in trying environmental conditions.
