To sum up, both of these cameras have the same sensor dimensions albeit different MP. You can expect the Pentax WG-3 GPS to deliver more detail because of its extra 2MP. Higher resolution will allow you to crop pictures a bit more aggressively. The more aged RS1500 is going to be disadvantaged when it comes to sensor technology.
