Quite often, it's hard to picture the difference in sensor measurements just by checking out specs. The visual underneath should give you a clearer sense of the sensor dimensions in the E-PL1 and WG-2 GPS.

All in all, both of those cameras posses different megapixels and different sensor measurements. The E-PL1 featuring a bigger sensor is going to make achieving shallower DOF simpler and the Pentax WG-2 GPS will show more detail utilizing its extra 4 Megapixels. Higher resolution can also help you crop photographs somewhat more aggressively. The older E-PL1 will be disadvantaged in sensor tech.
