Olympus E-520 vs Pentax K100D Sensor Comparison

Sometimes, its hard to visualize the contrast in sensor sizes merely by viewing specifications. The image here should offer you a clearer sense of the sensor measurements in the E-520 and K100D.

To sum up, the 2 cameras posses different megapixel count and different sensor sizes. The E-520 using its smaller sensor is going to make shooting shallower DOF trickier and the Olympus E-520 will result in greater detail having an extra 4 Megapixels. Higher resolution will also enable you to crop pictures somewhat more aggressively. The more recent E-520 provides an advantage in sensor innovation.
