POWER O.I.S. Lens from Panasonic is designed for Micro Four Thirds cameras, where it provides a 90-400mm equivalent focal length range. Benefitting the lens' reach is a sophisticated optical design that includes three extra-low dispersion elements to reduce color fringing and chromatic aberrations for notable clarity and sharpness. Complementing the optical performance is an apt POWER Optical Image Stabilizer system, which minimizes the appearance of camera shake and is also compatible with Dual I.S. for enhanced stabilization while shooting stills or video. A linear autofocus motor is also featured, for quick and quiet focusing performance, and the lens sports a splash and dustproof physical design to suit working in harsh climates.
