Oftentimes, it's hard to picture the contrast in sensor measurements simply by checking out a spec sheet. The visual underneath should give you a much better sense of the sensor sizes in the E-420 and A550.

Clearly, each of the cameras have different resolutions and different sensor measurements. The E-420 due to its smaller sensor is going to make achieving shallow DOF harder and the Sony A550 will provide more detail as a result of its extra 4 Megapixels. Greater resolution can also enable you to crop images a bit more aggressively. The older E-420 will be behind in sensor innovation.
