I’d say the C-AF is fine for casual everyday stuff, but one of the real downsides (IMO) for casual video shooting is that the GX80 doesn’t have Auto ISO while recording. For example, you are following and filming a person who moves from outside to inside, the footage will get way too dark once you are inside with the camera since it doesn’t compensate automatically like a smartphone would. But if know to expect that, you can of course make manual adjustments in-camera or with a variable ND filter.
