Panasonic FZ40 vs Pentax K-3 II Sensor Comparison

Plainly, both of the cameras offer different megapixels and different sensor measurements. The FZ40 because of its tinier sensor is going to make shooting shallow DOF trickier and the Pentax K-3 II will give greater detail having its extra 10 Megapixels. Higher resolution will allow you to crop shots a little more aggressively. The older FZ40 is going to be behind when it comes to sensor technology.
