Olympus E-P3 vs Pentax K10D Sensor Comparison

Often, it's difficult to visualize the contrast in sensor sizes just by researching technical specs. The picture below might offer you a far better sense of the sensor sizes in the E-P3 and K10D.

As you have seen, both the cameras feature different megapixel count and different sensor sizes. The E-P3 due to its smaller sensor is going to make shooting shallower DOF tougher and the Olympus E-P3 will render extra detail as a result of its extra 2MP. Greater resolution can also enable you to crop photos way more aggressively. The younger E-P3 should have an edge when it comes to sensor technology.
