Typically, it is hard to see the difference between sensor sizing merely by reviewing a spec sheet. The graphic below will give you a better sense of the sensor measurements in the E-PM1 and LZ20.

Clearly, both the cameras provide different megapixel count and different sensor sizing. The E-PM1 using its larger sensor will make shooting shallow depth of field simpler and the Panasonic LZ20 will offer extra detail using its extra 4 Megapixels. Greater resolution can also make it easier to crop pics more aggressively. The older E-PM1 is going to be behind in sensor technology.
