To sum up, the two cameras provide different resolutions and different sensor measurements. The ZS1 with its smaller sensor will make getting shallow DOF more challenging and the Pentax K20D will provide you with extra detail because of its extra 5 Megapixels. Higher resolution can also enable you to crop photographs more aggressively. The more modern ZS1 will have an advantage when it comes to sensor innovation.
