All in all, the 2 cameras come with different megapixels and different sensor dimensions. The WG-3 GPS having a smaller sensor will make getting shallow depth of field tougher and the Sigma Quattro will result in greater detail using its extra 13 Megapixels. Greater resolution will let you crop images a good deal more aggressively. The more aged WG-3 GPS will be disadvantaged in sensor innovation.
