As you have seen, the 2 cameras provide different megapixels and different sensor dimensions. The G1 with its tinier sensor is going to make shooting bokeh harder and the Pentax 645Z will give extra detail using its extra 39 Megapixels. Greater resolution will enable you to crop images more aggressively. The more aged G1 is going to be behind when it comes to sensor innovation.
