As you can see, both cameras feature different megapixel count and different sensor measurements. The E-M1 due to its tinier sensor will make achieving shallow depth of field tougher and the Olympus E-M1 will resolve greater detail as a result of its extra 1 Megapixels. Greater resolution can also let you crop photos way more aggressively. The more modern E-M1 will have a benefit when it comes to sensor tech.
