Olympus E-P1 vs Pentax WG-1 Sensor Comparison

Normally, it is tough to visualise the difference in sensor sizing purely by viewing technical specs. The visual underneath may give you a more clear sense of the sensor measurements in the E-P1 and WG-1.

As you can tell, each of these cameras come with different resolutions and different sensor sizing. The E-P1 because of its bigger sensor will make getting shallower depth of field easier and the Pentax WG-1 will provide you with extra detail as a result of its extra 2MP. Higher resolution can also let you crop pictures a good deal more aggressively. The older E-P1 will be disadvantaged in sensor tech.
