Olympus E-M10 vs Pentax K-S2 Sensor Comparison

Typically, it can be hard to visualise the difference in sensor sizing simply by researching a spec sheet. The photograph here might offer you a clearer sense of the sensor sizing in the E-M10 and K-S2.

Clearly, both of the cameras come with different megapixel count and different sensor sizing. The E-M10 having a smaller sensor will make getting shallower DOF tougher and the Pentax K-S2 will provide you with more detail using its extra 4 Megapixels. Higher resolution will let you crop photographs a good deal more aggressively. The older E-M10 will be disadvantaged when it comes to sensor tech.
