Olympus E-P2 vs Pentax K-7 Sensor Comparison

Oftentimes, it can be difficult to visualise the gap in sensor sizes merely by researching specifications. The pic underneath should offer you a clearer sense of the sensor sizing in the E-P2 and K-7.

To sum up, the two cameras enjoy different resolutions and different sensor sizes. The E-P2 using its smaller sensor will make getting shallower depth of field more difficult and the Pentax K-7 will result in greater detail having an extra 3MP. Greater resolution can also allow you to crop pics far more aggressively. The more modern E-P2 is going to have an edge in sensor technology.
