Sometimes, its hard to visualize the gap in sensor sizes purely by looking through technical specs. The pic underneath will give you a better sense of the sensor dimensions in the WG-3 and NEX-7.

As you can tell, both of these cameras provide different megapixels and different sensor sizes. The WG-3 because of its smaller sensor is going to make shooting shallower DOF more challenging and the Sony NEX-7 will result in greater detail due to its extra 8 Megapixels. Higher resolution will also let you crop shots more aggressively. The newer WG-3 provides an edge when it comes to sensor tech.
