As you can tell, both the cameras provide different resolutions and different sensor dimensions. The ZS25 using its smaller sensor is going to make getting shallow DOF more difficult and the Pentax 645D will render more detail with its extra 24MP. Higher resolution can also make it easier to crop shots more aggressively. The younger ZS25 provides an advantage with regard to sensor technology.
