More often than not, it's difficult to see the difference in sensor sizes purely by looking through specs. The picture below may offer you a more clear sense of the sensor sizing in the E-PM1 and GX850.

As you can plainly see, both of those cameras offer the same exact sensor sizing but not the same megapixels. You can expect to see the Panasonic GX850 to provide you with extra detail with its extra 4 Megapixels. Greater resolution will also help you crop images a little more aggressively. The more aged E-PM1 will be behind when it comes to sensor innovation.
