The WG-3 GPS was brought out 5 years after the DP1 which is quite a sizable difference as far as technology is concerned. Each of these cameras have different body design with the Pentax WG-3 GPS being a Compact camera and the Sigma DP1 being a Large Sensor Compact camera.

Before getting straight to a in-depth comparison, here is a simple highlight of how the WG-3 GPS scores against the DP1 in the way of portability, imaging, features and an overall mark.

Do not forget, the weight of an ILC will differ depending on the lens you have chosen at the time. Here is a front view measurement comparison of the WG-3 GPS and the DP1.

Using dimensions and weight, the portability rating of the WG-3 GPS and DP1 is 90 and 87 respectively.

Typically, it is hard to visualise the gap between sensor dimensions purely by going over technical specs. The pic below should give you a much better sense of the sensor sizing in the WG-3 GPS and DP1.

As you can tell, the two cameras provide different resolutions and different sensor dimensions. The WG-3 GPS because of its tinier sensor will make getting bokeh trickier and the Pentax WG-3 GPS will offer greater detail having its extra 11 Megapixels. Higher resolution will enable you to crop photographs more aggressively. The more modern WG-3 GPS is going to have a benefit when it comes to sensor tech.
