All in all, the two cameras have different resolutions and different sensor sizing. The WG-3 because of its tinier sensor is going to make getting shallower depth of field tougher and the Sigma fp will resolve extra detail as a result of its extra 9 Megapixels. Greater resolution will also make it easier to crop photos a bit more aggressively. The older WG-3 is going to be behind in sensor tech.
