Sometimes, it's tough to see the gap between sensor sizing just by checking a spec sheet. The visual here may give you a clearer sense of the sensor dimensions in the E-3 and S1.

As you can see, both the cameras come with different resolutions and different sensor sizing. The E-3 featuring a tinier sensor will make shooting shallow depth of field harder and the Panasonic S1 will give you extra detail due to its extra 14 Megapixels. Greater resolution will let you crop photos a good deal more aggressively. The older E-3 is going to be disadvantaged in sensor tech.
