Clearly, each of the cameras provide different megapixels and different sensor measurements. The WG-3 having a tinier sensor is going to make getting shallower DOF trickier and the Pentax WG-3 will resolve greater detail using its extra 6MP. Greater resolution can also help you crop pics more aggressively. The younger WG-3 should have a benefit when it comes to sensor technology.
