Pentax WG-3 GPS vs Sigma DP1s

Here, we are reviewing the Pentax WG-3 GPS vs Sigma DP1s, former being a Waterproof while the other is a Large Sensor Compact by rivals Pentax and Sigma. There exists a sizable gap between the image resolutions of the WG-3 GPS (16MP) and DP1s (5MP) and the WG-3 GPS (1/2.3") and DP1s (APS-C) boast totally different sensor sizes.

The WG-3 GPS was introduced 3 years later than the DP1s and that is quite a significant difference as far as technology is concerned. Both the cameras feature different body design with the Pentax WG-3 GPS being a Compact camera and the Sigma DP1s being a Large Sensor Compact camera.

Before diving straight to a step-by-step comparison, here is a brief highlight of how the WG-3 GPS scores against the DP1s in the way of portability, imaging, features and an overall grade.

Take into account, the weight of an ILC will change based on the lens you choose at the time. Here is a front view over all size comparison of the WG-3 GPS vs the DP1s.

Considering dimensions and weight, the portability grade of the WG-3 GPS and DP1s is 90 and 90 respectively.

Quite often, it is hard to envision the difference between sensor measurements only by reading through technical specs. The visual below should provide you a greater sense of the sensor dimensions in the WG-3 GPS and DP1s.

As you have seen, the two cameras come with different megapixels and different sensor measurements. The WG-3 GPS using its tinier sensor will make getting bokeh harder and the Pentax WG-3 GPS will give you more detail using its extra 11 Megapixels. Greater resolution will enable you to crop images a good deal more aggressively. The more recent WG-3 GPS will have a benefit when it comes to sensor innovation.
