Olympus E-P5 vs Pentax Q-S1 Sensor Comparison

Normally, it is very difficult to see the contrast between sensor measurements simply by going over technical specs. The visual here should provide you a better sense of the sensor measurements in the E-P5 and Q-S1.

As you have seen, both of the cameras provide different megapixels and different sensor measurements. The E-P5 with its bigger sensor will make achieving shallower DOF simpler and the Olympus E-P5 will deliver greater detail because of its extra 4MP. Higher resolution will let you crop shots more aggressively. The older E-P5 is going to be disadvantaged with regard to sensor innovation.
