The Panasonic GH4 can record 4K videos at 24 and 30 fps, however there is no Phase AF pixels in the newly designed sensor, but still there is some hope since the GH4 comes with a revised AF system that features 49 AF points and takes only 0.07 sec to AF on subject under normal lightning condition, other features include 3″ 1.04M dot fully articulating OLED display or an OLED EVF with over 2 million dots, Wi-Fi with NFC and a ‘silent mode’ which uses the electronic shutter only. Magnesium Alloy, Weather-Sealed Body.
