Often, it's difficult to visualize the gap in sensor measurements purely by viewing specs. The visual below will help provide you a clearer sense of the sensor dimensions in the E-620 and K-70.

All in all, both of the cameras have got different megapixels and different sensor measurements. The E-620 having a smaller sensor is going to make shooting shallower DOF more difficult and the Pentax K-70 will render more detail using its extra 12MP. Greater resolution will let you crop photos much more aggressively. The older E-620 will be behind in sensor tech.
