Olympus PEN-F vs Pentax K100D S Sensor Comparison

Quite often, it is very tough to picture the difference between sensor dimensions just by going over specifications. The picture below will help provide you a far better sense of the sensor sizing in the PEN-F and K100D S.

To sum up, both the cameras feature different megapixel count and different sensor dimensions. The PEN-F with its tinier sensor is going to make achieving shallower DOF harder and the Olympus PEN-F will deliver more detail having an extra 14 Megapixels. Higher resolution will let you crop pictures way more aggressively. The more modern PEN-F should have an advantage in sensor innovation.
