Often, its difficult to visualise the gap in sensor sizes merely by going through specifications. The image underneath might provide you a stronger sense of the sensor dimensions in the fp and A390.

Plainly, both of those cameras posses different megapixel count and different sensor sizes. The fp having a bigger sensor will make getting shallow depth of field easier and the Sigma fp will show more detail with its extra 11 Megapixels. Higher resolution will also help you crop photographs somewhat more aggressively. The more recent fp is going to have an advantage with regard to sensor tech.
