Olympus E-P2 vs Pentax K100D Sensor Comparison
Typically, its difficult to visualise the difference between sensor measurements purely by reading through specs. The visual here might give you a far better sense of the sensor measurements in the E-P2 and K100D.
As you can plainly see, each of these cameras come with different megapixel count and different sensor measurements. The E-P2 due to its tinier sensor will make getting shallow DOF trickier and the Olympus E-P2 will give extra detail having its extra 6 Megapixels. Higher resolution will make it easier to crop pictures a good deal more aggressively. The newer E-P2 will have an edge in sensor innovation.
