Olympus E-PL1 vs Pentax K100D S Sensor Comparison

As you can see, both of the cameras offer different megapixel count and different sensor sizes. The E-PL1 due to its tinier sensor will make achieving shallow depth of field more difficult and the Olympus E-PL1 will give greater detail having its extra 6 Megapixels. Higher resolution will also allow you to crop photographs a little more aggressively. The newer E-PL1 is going to have an edge with regard to sensor technology.
