To sum up, both of the cameras enjoy different megapixel count and different sensor dimensions. The GX1 due to its smaller sensor is going to make getting shallower DOF more difficult and the Pentax K-3 will provide more detail having its extra 8 Megapixels. Greater resolution will also help you crop photos far more aggressively. The more aged GX1 will be disadvantaged in sensor innovation.
