Take into consideration, the weight of an ILC will differ based on the lens you have attached during that time. Underneath is a front view sizing comparison of the G1 against the WG-1 GPS.

Using dimensions and weight, the portability score of the G1 and WG-1 GPS is 82 and 93 respectively.

Normally, it is very difficult to visualise the contrast between sensor measurements purely by looking at specifications. The graphic underneath may offer you a better sense of the sensor sizes in the G1 and WG-1 GPS.

To sum up, both cameras come with different megapixels and different sensor measurements. The G1 due to its larger sensor will make getting shallower DOF simpler and the Pentax WG-1 GPS will give extra detail utilizing its extra 2 Megapixels. Greater resolution will also enable you to crop pics a good deal more aggressively. The older G1 is going to be disadvantaged in sensor tech.
