Olympus E-PM1 vs Sony A99 II Sensor Comparison

Normally, it can be hard to visualise the contrast between sensor sizing only by going over a spec sheet. The visual here may give you a greater sense of the sensor sizing in the E-PM1 and A99 II.

Clearly, each of the cameras come with different resolutions and different sensor sizing. The E-PM1 having a tinier sensor will make shooting shallower DOF tougher and the Sony A99 II will offer greater detail using its extra 30 Megapixels. Greater resolution will help you crop photos a good deal more aggressively. The older E-PM1 is going to be behind when it comes to sensor tech.
