Often, it is very tough to see the gap between sensor dimensions merely by going over a spec sheet. The picture below will help provide you a stronger sense of the sensor sizes in the TG-3 and G3.

As you can see, both of those cameras have the same resolution albeit not the same sensor dimensions. The TG-3 includes the tinier sensor which is going to make obtaining shallow depth of field trickier. The younger TG-3 is going to have a benefit when it comes to sensor innovation.
