Quite often, its hard to envision the difference in sensor sizing just by seeing a spec sheet. The visual here will give you a far better sense of the sensor dimensions in the G1 and RZ10.

As you can see, each of these cameras have different megapixels and different sensor sizing. The G1 featuring a bigger sensor will make achieving bokeh easier and the Pentax RZ10 will provide greater detail having its extra 2MP. Higher resolution will let you crop photographs a bit more aggressively. The older G1 will be behind in sensor innovation.
