Sometimes, it's tough to imagine the contrast in sensor sizing only by researching technical specs. The photograph underneath should provide you a clearer sense of the sensor dimensions in the E-PM2 and G1.

As you can tell, both cameras have the same sensor dimensions but different resolution. You should expect to see the Olympus E-PM2 to provide you with greater detail using its extra 4MP. Greater resolution can also enable you to crop photos a bit more aggressively. The newer E-PM2 provides a benefit when it comes to sensor innovation.
