Olympus E-420 vs Pentax VS20 Sensor Comparison

		

		

			
Oftentimes, it is difficult to visualize the difference in sensor dimensions merely by seeing technical specs. The image underneath should provide you a greater sense of the sensor sizes in the E-420 and VS20.
As you can tell, each of these cameras come with different resolutions and different sensor dimensions. The E-420 using its larger sensor is going to make shooting shallow DOF less difficult and the Pentax VS20 will show greater detail because of its extra 6 Megapixels. Greater resolution will let you crop pics a good deal more aggressively. The more aged E-420 will be behind with regard to sensor technology.
