Pentax WG-3 GPS vs Sigma DP2

Let's examine more closely at the Pentax WG-3 GPS versus Sigma DP2, former being a Waterproof while the latter is a Large Sensor Compact by brands Pentax and Sigma. There is a large difference between the sensor resolutions of the WG-3 GPS (16MP) and DP2 (5MP) and the WG-3 GPS (1/2.3") and DP2 (APS-C) feature different sensor measurements.

Take into consideration, the weight of an ILC will vary depending on the lens you have attached at that moment. Following is the front view dimensions comparison of the WG-3 GPS compared to the DP2.

Factoring in size and weight, the portability score of the WG-3 GPS and DP2 is 90 and 86 respectively.

Oftentimes, it can be hard to imagine the difference between sensor sizing merely by reviewing technical specs. The visual here will provide you a much better sense of the sensor dimensions in the WG-3 GPS and DP2.

As you can tell, both the cameras offer different megapixel count and different sensor sizing. The WG-3 GPS with its tinier sensor is going to make getting shallower depth of field trickier and the Pentax WG-3 GPS will deliver extra detail because of its extra 11MP. Higher resolution can also make it easier to crop pictures a little more aggressively. The more recent WG-3 GPS should have a benefit with regard to sensor innovation.
