The first reliable rumours are coming in about the GH5. According to 43Rumors it will not be ready for Photokina, instead we might be looking at an early 2017 release date. They also appear to be confident about two other aspects – no extra crop of the sensor when shooting 4K and the codec has been bumped up to 10bit 4:2:2 internally!

This is 10bit 4:2:2 and oversampled internally from 4K, a bit like on the Sony FS700 but for only $1699. The video above shows how to setup the camera for recording 10bit 1080p onto the Atomos Blade.

Based on a pre-production model Since the GH1 I have been shooting with Panasonic’s mirrorless system for video. Without this series of affordable cameras my early work as a cinematographer and filmmaker simply wouldn’t be the same. The GH4 marks a much needed major leap for the line, the first to shoot 4K to an efficient internal codec AND output 10bit 4:2:2 1080p over HDMI to an affordable external recorder…
