Olympus 1s vs Pentax RS1500 Sensor Comparison

Sometimes, its difficult to envision the gap in sensor measurements purely by viewing a spec sheet. The graphic here might provide you a more clear sense of the sensor sizing in the 1s and RS1500.

As you can see, both the cameras have different resolutions and different sensor measurements. The 1s having a larger sensor will make shooting shallower DOF less difficult and the Pentax RS1500 will render extra detail with its extra 2 Megapixels. Greater resolution will help you crop photos a bit more aggressively. The younger 1s will have an edge in sensor technology.
