Pentax K20D vs Pentax W80 Sensor Comparison

Normally, it is very difficult to visualize the gap in sensor sizing only by checking out technical specs. The graphic here should give you a better sense of the sensor dimensions in the K20D and W80.

As you have seen, each of the cameras have got different resolutions and different sensor sizing. The K20D having a larger sensor is going to make achieving shallower DOF less difficult and the Pentax K20D will show greater detail having an extra 3 Megapixels. Greater resolution will let you crop pics much more aggressively. The older K20D will be disadvantaged with regard to sensor innovation.
