Clearly, each of the cameras feature different megapixels and different sensor dimensions. The E-PL6 with its smaller sensor is going to make achieving shallower depth of field tougher and the Pentax 645D will render more detail because of its extra 24MP. Greater resolution can also allow you to crop pics way more aggressively. The fresher E-PL6 provides a benefit when it comes to sensor technology.
