Olympus E-P2 vs Pentax Q-S1 Sensor Comparison

Normally, it is tough to visualise the contrast between sensor measurements merely by checking specifications. The graphic underneath may provide you a far better sense of the sensor sizes in the E-P2 and Q-S1.

Plainly, both of the cameras provide the same megapixels albeit not the same sensor measurements. The E-P2 offers the bigger sensor which should make getting shallow DOF easier. The older E-P2 is going to be disadvantaged when it comes to sensor innovation.
