Usually, it can be difficult to imagine the difference between sensor measurements just by looking at technical specs. The photograph below might give you a more clear sense of the sensor sizes in the G5 and DP2 Quattro.

As you can tell, the two cameras offer different megapixel count and different sensor measurements. The G5 using its tinier sensor is going to make shooting shallow depth of field trickier and the Sigma DP2 Quattro will resolve greater detail because of its extra 4 Megapixels. Greater resolution will make it easier to crop photos a little more aggressively. The older G5 is going to be disadvantaged with regard to sensor tech.
