Panasonic ZS45 vs Pentax K100D S Sensor Comparison

As you can see, the two cameras come with different megapixels and different sensor measurements. The ZS45 due to its tinier sensor is going to make getting shallow DOF more difficult and the Panasonic ZS45 will give greater detail having its extra 10 Megapixels. Higher resolution will enable you to crop shots a good deal more aggressively. The fresher ZS45 provides an edge with regard to sensor technology.
