To sum up, each of the cameras enjoy different resolutions and different sensor measurements. The K20D having a larger sensor is going to make shooting shallow DOF easier and the Sony WX500 will produce more detail using its extra 3MP. Greater resolution will also allow you to crop pics far more aggressively. The older K20D will be behind in sensor technology.
