Looking at dimensions and weight, the portability grade of the SD4000 IS and WG-3 GPS is 94 and 90 respectively.

Typically, it is very tough to imagine the gap between sensor sizing just by looking at specifications. The visual underneath may provide you a greater sense of the sensor sizes in the SD4000 IS and WG-3 GPS.

Plainly, both of the cameras enjoy the same exact sensor sizing but different megapixels. You should anticipate the Pentax WG-3 GPS to resolve extra detail with its extra 6MP. Greater resolution will also make it easier to crop images far more aggressively. The older SD4000 IS is going to be behind with regard to sensor innovation.
