Here is the full review from Dpreview. The camera gets no Award at all with the following conclusion:
The G100 is designed to be a camera for vloggers and content creators but its severe crop in video (especially if you want stabilization) and its inconsistent AF undermine it for that task. It’s a capable enough small interchangeable lens camera but one whose special features aren’t particularly usable.
Autofocus really is the issue here. Hope Panasonic can find some magic trick to fix this on the GH6.
