As you can plainly see, both of those cameras provide different resolutions and different sensor dimensions. The SZ7 having a smaller sensor is going to make achieving shallow DOF trickier and the Panasonic SZ7 will provide more detail with its extra 2MP. Higher resolution can also allow you to crop shots more aggressively. The younger SZ7 should have an edge with regard to sensor technology.
