Am I just getting old, or was video AF of GH1 already nearly as good as G7/G80/GH5? Please show me some examples of GH1 AF. The best I got from YouTube is this: https://youtu.be/FCgOYCu47r4

NOT EVEN CLOSE. I watch your video and counted the seconds. It took Gh1 a slow 7s to achieve focus on her face. You're better off manual focusing. Luckily newer Panasonic are much faster than this.

Did you listen the audio? The camera was MF in the beginning and it instantaneously focused to her face when the mode dial was set to AF.

The problem is not af speed when it get impulse to do so. Tap the screen and it will af very fast. Real problem is not speed of afying but the decision phase when camera has to make a decision on its own when to start. And next to it - how it minimize overshot and AF wobbling + maximize smoothness . Reducing it just to speed it simplicisting the whole thing.

You are absolutely correct. Faster does not mean better. When wobbling occurs, it's much more distracting on GH1 than on newer cameras.

I went trough my archive and the best videos showing how GH1 video AF works are shown below. Judge yourselves and think how good GH5 AF must be, because it is a forum fact that Panasonic has improved it a lot during the past 8 years...
