Often, it can be tough to envision the gap between sensor sizing simply by reviewing a spec sheet. The graphic here will help offer you a much better sense of the sensor dimensions in the SZ3 and K20D.

Clearly, the 2 cameras come with different megapixel count and different sensor sizing. The SZ3 with its tinier sensor will make shooting bokeh tougher and the Panasonic SZ3 will offer you more detail having an extra 1MP. Higher resolution will allow you to crop pictures a good deal more aggressively. The more recent SZ3 is going to have an advantage in sensor innovation.
