Sometimes, its hard to visualize the contrast between sensor measurements merely by reading specifications. The visual below will offer you a stronger sense of the sensor sizes in the K20D and S1.
Plainly, each of the cameras have got different megapixel count and different sensor measurements. The K20D with its larger sensor is going to make achieving shallower depth of field easier and the Pentax K20D will deliver more detail using its extra 1MP. Greater resolution can also make it easier to crop pics much more aggressively. The older K20D is going to be disadvantaged with regard to sensor innovation.
