Oftentimes, its tough to see the contrast between sensor sizing only by reading a spec sheet. The photograph below may offer you a greater sense of the sensor sizing in the K-7 and WX150.

Clearly, each of the cameras come with different megapixels and different sensor sizing. The K-7 using its larger sensor will make getting shallow depth of field simpler and the Sony WX150 will deliver greater detail using its extra 3MP. Greater resolution will make it easier to crop photos a good deal more aggressively. The older K-7 is going to be behind with regard to sensor tech.
