As you can tell, both of these cameras come with different megapixels and different sensor sizes. The WG-3 GPS due to its smaller sensor is going to make shooting shallow DOF trickier and the Pentax WG-3 GPS will produce extra detail having its extra 13 Megapixels. Greater resolution can also let you crop pics a good deal more aggressively. The fresher WG-3 GPS should have an advantage when it comes to sensor innovation.
