The Panasonic GH5 ushered the era of 10-bit video recording on a portable prosumer interchangeable lens camera for the first time. Panasonic promised some features which at launch would not make the cut but would be added when firmware was released that would improve the spec sheet. The new 1.1 version of the Firmware will enable 10bit recording on 1080p 24p, 25p, 29.98, 29.97p, 59.94p & 50p all at 100 Mbps.
While the camera offered 10 Bit recording at 4k from the get go it was not available above 29.97fps which left the 60fps 4k mode out in the cold for the increased color space. The update and all subsequent ones will also do not allow 10 Bit to be used above 30p in 4k so the 60fps UHD spec will remain at 4:2:0 8 Bit color.[...]
