Panasonic introduces two models in the UX Series of professional 4K camcorders. The UX Series is the successor to Panasonic's AVCCAM Series of professional AVCHD camcorders. Given the increasing demand for 4K video content, the UX Series is designed to facilitate the upward shift to 4K for professional image production. The UX series offer specifications, functions and designs that provide the same level of mobility, operability and workflow tracking ability as conventional HD handheld camcorders. The AG-UX180 premium model features the industry's widest-angle 24mm (at 4K/FHD) and optical 20x zoom, and supports 4K 24p, UHD 60p/50p, FHD 60p/50p recording, 120fps/100fps HD super slow, dual codec recording (UHD/FHD), IR recording in dark places, 3G-SDI output, and TC PRESET input/output. The AG-UX90 standard model offers wide-angle 24.5mm (at FHD) and optical 15x zoom, and supports UHD 30p and FHD 60p recording.
