Normally, it is very difficult to visualize the difference between sensor sizing only by checking specifications. The graphic underneath should offer you a clearer sense of the sensor sizing in the GF3 and K-7.

To sum up, both of those cameras come with different resolutions and different sensor sizing. The GF3 featuring a tinier sensor is going to make getting shallower depth of field more difficult and the Pentax K-7 will give extra detail having its extra 3 Megapixels. Higher resolution will also let you crop pictures a good deal more aggressively. The younger GF3 should have an advantage with regard to sensor innovation.
