The Panasonic LUMIX GH5s is excellent for studio video. It records both 4k and Cinema 4k at up to 60p. It can also record 10-bit 4:2:2 video internally at frame rates up to 30p, allowing you to take full advantage of the sensor's dynamic range.
10-bit 4:2:2 internal recording up to 30p., No recording time limit., 4k and C4k up to 60 fps., Impressive video quality.
Not the most portable camera., Mediocre autofocus in video.
