I believe the Canon g7x Mark 2 is a step above the Canon g7x. Canon g7x = meh autofocus. Canon g7x Mark II = better autofocus. But Sony is still the king. The Canon g7x Mark 2 has 31 autofocus points, whereas the latest Sony rx100v has 315 autofocus points. Granted, in many situations it is probably over kill, but I have seen side by side comparisons where the Sony just snaps into focus almost instantly while the Canon struggles to find the subject in the frame.
