As you can see, both the cameras have different megapixel count and different sensor sizes. The PEN-F using its tinier sensor is going to make shooting shallow DOF more challenging and the Olympus PEN-F will offer you extra detail with its extra 8MP. Greater resolution will also let you crop images a bit more aggressively. The more aged PEN-F is going to be disadvantaged in sensor innovation.
