Plainly, each of the cameras enjoy different megapixel count and different sensor dimensions. The K20D having a larger sensor will make achieving shallow DOF less difficult and the Sony WX150 will give you greater detail with its extra 3MP. Greater resolution will let you crop pics far more aggressively. The more aged K20D is going to be disadvantaged in sensor innovation.
