GH6 video quality at high ISO

When the Lumix GH5 arrived in 2017, I thought it was the first Micro Four Thirds camera to be truly usable at ISO 6400. Of course you still get better image quality at lower ISO, but when you need high ISO, it still delivers well.

The Lumix GH6 has an even newer sensor and image processor, so you might expect better performance. I have compared the two cameras by using the same lens on both, the Lumix G 14-42mm f/3.5-5.6 zoom lens. I had both mounted to a bracket so that they can capture the same field of view in 4K mode, 60p, 1/60s shutter:

Here is the comparison:

But the Lumix GH6 has another trick up its sleeve: The "Dynamic Range Boost", or "DR Boost". With this feature, the camera will process the input signals at two different gains at the same time, and then combining them to give better overall dynamic range.

This works in most video modes, but only from ISO 800 and upwards. I used ISO 6400 here, with the Lumix G 14-42mm lens, at f/5.6 and 60 frames per second:

I think these examples show that the Lumix GH6 is even more usable at high ISO. The video looks more clean at ISO 6400, compared with the Lumix GH5.
