Olympus E-500 vs Pentax K20D Sensor Comparison
Sometimes, it is tough to picture the gap between sensor sizes simply by checking a spec sheet. The pic underneath will help give you a stronger sense of the sensor measurements in the E-500 and K20D.
Clearly, both the cameras enjoy different megapixel count and different sensor sizes. The E-500 having a tinier sensor is going to make achieving shallow DOF harder and the Pentax K20D will give greater detail having an extra 7 Megapixels. Higher resolution will also make it easier to crop shots far more aggressively. The more aged E-500 is going to be disadvantaged in sensor technology.
