Usually, it is difficult to envision the contrast between sensor measurements just by looking at a spec sheet. The visual below might provide you a greater sense of the sensor dimensions in the K-1 and E90.

As you can see, both of these cameras enjoy different megapixels and different sensor measurements. The K-1 having a larger sensor will make shooting shallow DOF easier and the Pentax K-1 will give extra detail using its extra 26 Megapixels. Greater resolution can also let you crop pics far more aggressively. The fresher K-1 will have an edge with regard to sensor innovation.
