Olympus E-620 vs Pentax K-S2 Sensor Comparison

All in all, both of those cameras enjoy different resolutions and different sensor sizes. The E-620 with its tinier sensor is going to make shooting shallow DOF tougher and the Pentax K-S2 will deliver greater detail having an extra 8 Megapixels. Higher resolution will also enable you to crop shots far more aggressively. The more aged E-620 is going to be disadvantaged when it comes to sensor innovation.
