Olympus E-P1 vs Pentax WG-2 Sensor Comparison

Oftentimes, its tough to picture the contrast in sensor dimensions simply by viewing technical specs. The picture here should provide you a far better sense of the sensor sizes in the E-P1 and WG-2.

As you can tell, both of those cameras posses different resolutions and different sensor dimensions. The E-P1 having a bigger sensor is going to make achieving shallower DOF easier and the Pentax WG-2 will render more detail with its extra 4 Megapixels. Higher resolution will let you crop photographs somewhat more aggressively. The more aged E-P1 will be disadvantaged when it comes to sensor tech.
