Sometimes, it is difficult to visualize the gap between sensor dimensions purely by going over a spec sheet. The pic underneath should offer you a clearer sense of the sensor sizing in the E-P3 and K-70.
Clearly, both of the cameras provide different megapixel count and different sensor dimensions. The E-P3 having a tinier sensor is going to make getting shallow depth of field trickier and the Pentax K-70 will offer you extra detail because of its extra 12MP. Greater resolution will also let you crop pics more aggressively. The more aged E-P3 is going to be behind when it comes to sensor innovation.
