Sometimes, it is tough to visualise the gap between sensor sizing just by reading specifications. The visual below will give you a more clear sense of the sensor measurements in the E-M1 and G1.

To sum up, both the cameras provide the same sensor dimensions albeit not the same megapixels. You should count on the Olympus E-M1 to deliver more detail because of its extra 4MP. Higher resolution will enable you to crop pictures more aggressively. The more modern E-M1 will have a benefit when it comes to sensor innovation.
