Often, it is very hard to visualise the contrast between sensor sizing only by looking at specifications. The visual below might provide you a far better sense of the sensor sizing in the E-520 and G3.

Plainly, both cameras posses the exact same sensor measurements but not the same megapixels. You can expect to see the Panasonic G3 to give extra detail because of its extra 6 Megapixels. Greater resolution will also enable you to crop images somewhat more aggressively. The older E-520 is going to be disadvantaged with regard to sensor tech.
