Normally, it can be tough to picture the difference in sensor sizing purely by looking through a spec sheet. The graphic below will help provide you a more clear sense of the sensor sizing in the E-30 and K-3 III.

Clearly, both the cameras feature different megapixels and different sensor sizing. The E-30 due to its smaller sensor is going to make achieving shallower DOF harder and the Pentax K-3 III will render more detail due to its extra 14 Megapixels. Higher resolution will enable you to crop pictures way more aggressively. The older E-30 will be behind when it comes to sensor tech.
