As you can plainly see, both of the cameras provide different resolutions and different sensor measurements. The E-PM1 because of its smaller sensor is going to make achieving shallower DOF trickier and the Ricoh GR III will provide you with greater detail having its extra 12 Megapixels. Higher resolution will also enable you to crop pictures more aggressively. The older E-PM1 will be disadvantaged in sensor innovation.
