As you can tell, both cameras have the same sensor dimensions but different megapixels. You should expect to see the Panasonic GX1 to offer you extra detail because of its extra 4 Megapixels. Greater resolution will also enable you to crop images a bit more aggressively. The more aged E-P1 is going to be behind in sensor tech.
