All in all, both the cameras provide different megapixels and different sensor measurements. The K100D S featuring a bigger sensor is going to make shooting shallower DOF less difficult and the Pentax WG-1 GPS will offer extra detail having its extra 8MP. Higher resolution will also allow you to crop photographs more aggressively. The older K100D S is going to be behind with regard to sensor technology.
