Oftentimes, it's difficult to visualise the difference between sensor sizing purely by reading through technical specs. The graphic here will give you a more clear sense of the sensor sizing in the E-400 and ZS20.

As you have seen, both of those cameras feature different megapixel count and different sensor sizing. The E-400 due to its larger sensor will make achieving shallow DOF less difficult and the Panasonic ZS20 will give more detail due to its extra 4MP. Greater resolution will also help you crop images way more aggressively. The older E-400 is going to be disadvantaged when it comes to sensor tech.
