Panasonic Lumix DC-G100 (Lumix DC-G110) Review
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.
