As you can plainly see, the two cameras offer different resolutions and different sensor measurements. The ZS15 because of its smaller sensor is going to make shooting shallower depth of field trickier and the Pentax K20D will provide you with greater detail as a result of its extra 3 Megapixels. Higher resolution can also make it easier to crop photographs a little more aggressively. The younger ZS15 provides an advantage with regard to sensor innovation.
