Olympus E-330 vs Pentax K20D Sensor Comparison

Quite often, it is very hard to picture the gap between sensor sizes simply by reading specifications. The picture here should provide you a much better sense of the sensor dimensions in the E-330 and K20D.

To sum up, the 2 cameras come with different megapixels and different sensor sizes. The E-330 featuring a tinier sensor is going to make achieving shallow depth of field trickier and the Pentax K20D will deliver extra detail having its extra 8 Megapixels. Higher resolution will also make it easier to crop shots a good deal more aggressively. The more aged E-330 is going to be disadvantaged with regard to sensor technology.
