With a fast F2.8 aperture, effective Power O.I.S., and robust design, this lens is built for professional use under harsh conditions. High resolution, high contrast images are achieved from corner to corner thanks to Panasonic’s highly evolved cutting-edge optical technologies, while distortion and chromatic aberrations are suppressed by the inclusion of UED (Ultra Extra-Low Dispersion Lenses) lenses. A three magnets linear motor and 240 fps (max.) sensor drive enables a high-speed, high-precision contrast AF system, even in 4K video.
