Generally, it can be tough to picture the gap in sensor sizes merely by going through technical specs. The pic here may give you a better sense of the sensor sizes in the E-3 and K-3 III.

As you can tell, each of these cameras come with different resolutions and different sensor sizes. The E-3 having a smaller sensor is going to make shooting shallow depth of field harder and the Pentax K-3 III will show greater detail using its extra 16 Megapixels. Higher resolution can also make it easier to crop shots a good deal more aggressively. The more aged E-3 will be behind with regard to sensor innovation.
