The Lumix G Vario 14-140mm f/3.5-5.6 II ASPH. POWER O.I.S. from Panasonic is designed for Micro Four Thirds mirrorless cameras and provides a 28-280mm equivalent focal length range. The lens construction incorporates three aspherical elements and a pair of extra-low dispersion elements to minimize chromatic aberrations and distortions for greater image sharpness and clarity. This lens also features a stepping motor for fast and quiet autofocus performance that benefits both stills and movie shooting. An internal focusing design maintains the overall lens length during operation and also quickens focusing speeds. Three aspherical elements and two extra-low dispersion elements combine to minimize spherical and chromatic aberrations, as well as distortion, throughout the zoom range for increased clarity and sharpness. The stepping motor provides smooth and near-silent autofocus that pairs with an inner focusing design for quick performance. The AF system is also compatible with Lumix cameras' high-speed contrast-detection systems for focusing speeds up to 240 fps.
