Plainly, both of the cameras come with different megapixels and different sensor measurements. The GF6 having a smaller sensor is going to make getting shallow DOF trickier and the Pentax 645D will produce more detail with its extra 24MP. Higher resolution will help you crop pictures a good deal more aggressively. The more recent GF6 provides an edge when it comes to sensor tech.
