Panasonic has introduced two M4/3 system dedicated power zoom lenses: one is the compact Lumix GX PZ 14-42mm F/3.5-5.6 standard zoom lens, and the other is the Lumix GX 45-175mm F/4-5.6 telephoto lens. Both lenses feature Panasonic's nano coating, use aspherical and ED lens elements, have a new optical image stabilization function, and are equipped with an innovative electronic push-button for quiet and rapid zooming. Panasonic's nano coating reduces ghosting and flaring, resulting in clearer and more transparent images; the new optical image stabilization enhances the sensitivity of the gyro sensor, improving the issue of camera shake. The electronic push-button zoom allows for quick and silent zooming, making it convenient to use while recording videos.
