Often, it's tough to imagine the contrast in sensor dimensions only by going through a spec sheet. The picture underneath may offer you a better sense of the sensor measurements in the PEN-F and K20D.

As you can see, both the cameras have different megapixels and different sensor dimensions. The PEN-F featuring a smaller sensor is going to make shooting shallower DOF trickier and the Olympus PEN-F will produce greater detail as a result of its extra 5 Megapixels. Greater resolution will let you crop images a bit more aggressively. The more recent PEN-F provides a benefit when it comes to sensor innovation.
