Clearly, the two cameras feature different megapixel count and different sensor measurements. The TG-4 featuring a smaller sensor will make achieving shallow depth of field more difficult and the Pentax K-S2 will provide greater detail due to its extra 4 Megapixels. Higher resolution will also make it easier to crop pictures way more aggressively.
