Olympus SP-100 vs Pentax 645D Sensor Comparison

Oftentimes, it is very hard to envision the gap between sensor dimensions just by reading a spec sheet. The pic here should offer you a clearer sense of the sensor measurements in the SP-100 and 645D.

As you can see, the 2 cameras have different resolutions and different sensor dimensions. The SP-100 because of its tinier sensor will make shooting bokeh more difficult and the Pentax 645D will deliver extra detail due to its extra 24 Megapixels. Higher resolution will enable you to crop shots a bit more aggressively. The fresher SP-100 is going to have a benefit in sensor technology.
