Panasonic ZS7 vs Pentax K20D Sensor Comparison

Usually, it is hard to picture the difference in sensor sizes merely by checking out a spec sheet. The image here will provide you a better sense of the sensor sizes in the ZS7 and K20D.

Clearly, both cameras come with different megapixel count and different sensor sizes. The ZS7 because of its smaller sensor is going to make achieving shallow DOF tougher and the Pentax K20D will produce more detail having its extra 3 Megapixels. Higher resolution will also enable you to crop pictures a good deal more aggressively. The newer ZS7 provides an advantage when it comes to sensor technology.
