As you can tell, the 2 cameras feature different megapixel count and different sensor dimensions. The TG-820 iHS with its smaller sensor will make achieving shallow depth of field harder and the Pentax K-S2 will produce more detail with its extra 8 Megapixels. Higher resolution can also help you crop pictures way more aggressively. The more aged TG-820 iHS will be disadvantaged when it comes to sensor technology.
