Often, it's tough to picture the contrast in sensor dimensions purely by going through a spec sheet. The image underneath will offer you a better sense of the sensor measurements in the WG-3 and A450.

Clearly, both of these cameras offer different megapixels and different sensor dimensions. The WG-3 using its smaller sensor is going to make achieving shallower depth of field more challenging and the Pentax WG-3 will produce greater detail having an extra 2 Megapixels. Higher resolution will also let you crop photographs a little more aggressively. The fresher WG-3 should have an edge with regard to sensor innovation.
