Usually, it can be hard to visualize the difference in sensor sizing simply by viewing a spec sheet. The photograph below will provide you a greater sense of the sensor measurements in the E-620 and K20D.

Clearly, both the cameras enjoy different megapixel count and different sensor sizing. The E-620 having a smaller sensor is going to make achieving bokeh tougher and the Pentax K20D will result in more detail using its extra 3 Megapixels. Higher resolution can also make it easier to crop shots far more aggressively. The newer E-620 should have an advantage with regard to sensor technology.
