Often, it is very tough to visualize the difference between sensor sizing simply by reviewing technical specs. The visual underneath might provide you a more clear sense of the sensor sizing in the TG-850 iHS and K-S2.

As you have seen, both of those cameras come with different resolutions and different sensor sizing. The TG-850 iHS with its tinier sensor is going to make achieving shallower DOF trickier and the Pentax K-S2 will offer extra detail having an extra 4MP. Higher resolution can also allow you to crop pictures a good deal more aggressively. The older TG-850 iHS is going to be disadvantaged in sensor innovation.
