As you can plainly see, both the cameras posses different megapixel count and different sensor sizing. The PEN-F featuring a larger sensor is going to make getting shallower DOF simpler and the Olympus PEN-F will offer you greater detail due to its extra 10MP. Greater resolution will allow you to crop photos somewhat more aggressively. The newer PEN-F should have a benefit when it comes to sensor tech.
