In many cases, it's hard to envision the contrast between sensor measurements simply by checking specs. The visual here will help offer you a far better sense of the sensor measurements in the ZS3 and WG-1 GPS.

All in all, both of these cameras have got the exact same sensor measurements but not the same resolution. You should anticipate the Pentax WG-1 GPS to give you more detail with its extra 4 Megapixels. Greater resolution will also allow you to crop photos much more aggressively. The older ZS3 is going to be disadvantaged with regard to sensor technology.
