Normally, it is difficult to picture the contrast in sensor measurements merely by researching specs. The photograph below will help provide you a clearer sense of the sensor measurements in the K-5 and QX100.

All in all, each of the cameras enjoy different resolutions and different sensor measurements. The K-5 having a larger sensor is going to make getting shallower DOF simpler and the Sony QX100 will render extra detail with its extra 4MP. Greater resolution can also enable you to crop pics far more aggressively. The older K-5 will be disadvantaged in sensor tech.
