All in all, each of the cameras come with different megapixels and different sensor measurements. The TG-610 using its tinier sensor will make achieving shallower DOF harder and the Sony A7 III will give greater detail having an extra 10MP. Higher resolution will enable you to crop pictures a good deal more aggressively. The older TG-610 is going to be behind when it comes to sensor innovation.
