Typically, it's difficult to visualise the contrast between sensor dimensions simply by going over a spec sheet. The picture here might give you a clearer sense of the sensor sizes in the K-01 and E90.

As you can see, both of these cameras feature different resolutions and different sensor dimensions. The K-01 with its bigger sensor will make achieving shallow DOF simpler and the Pentax K-01 will offer extra detail with its extra 6 Megapixels. Higher resolution will let you crop pictures way more aggressively. The younger K-01 is going to have an edge with regard to sensor tech.
