Clearly, each of these cameras come with different megapixel count and different sensor dimensions. The WG-3 because of its smaller sensor is going to make getting shallow DOF more difficult and the Pentax WG-3 will render greater detail due to its extra 11 Megapixels. Greater resolution can also allow you to crop images a good deal more aggressively. The more modern WG-3 provides an advantage when it comes to sensor tech.
