As an evolutionary intermediate step on the way to the upcoming GH6, Panasonic had improved the GH5 in early summer and relaunched it as the GH5 II. In addition to new live streaming features, it has more effective 5-axis image stabilization, better autofocus, and is also capable of recording at up to 60p at full sensor resolution and full debayering internally at 10 bit. We had already looked at the latter in a quick test.

However, something also seems to have changed in the camera's dynamic range, although the GH5 II basically uses the same sensor as its predecessor. Thus Photons to photos recently sensor measurements published, in which the GH5 II scores with the DR around scarcely one aperture step better than the GH5:
This seems puzzling at first glance, but Panasonic actually mentioned a new anti-reflective coating on the sensor at the camera's launch, which is supposed to increase the dynamic range of the GH5 II. It seems that this adjustment screw can actually be used to get a higher light yield.
