Olympus PEN-F vs Pentax K100D S

Let's look a bit more closely at the Olympus PEN-F vs Pentax K100D S, one is a Advanced Mirrorless and the latter is a Entry-Level DSLR by manufacturers Olympus and Pentax. There exists a significant gap between the sensor resolutions of the PEN-F (20MP) and K100D S (6MP) and the PEN-F (Four Thirds) and K100D S (APS-C) have different sensor measurements.

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.
