Pentax WG-3 vs Sigma DP1s

The following is a thorough assessment of the Pentax WG-3 versus Sigma DP1s, one is a Waterproof and the latter is a Large Sensor Compact by competitors Pentax and Sigma. There is a sizeable difference among the image resolutions of the WG-3 (16MP) and DP1s (5MP) and the WG-3 (1/2.3") and DP1s (APS-C) use totally different sensor sizing.

The WG-3 was revealed 3 years after the DP1s which is a fairly large gap as far as camera tech is concerned. Both cameras come with different body type with the Pentax WG-3 being a Compact camera and the Sigma DP1s being a Large Sensor Compact camera.

Before getting straight into a in-depth comparison, below is a quick synopsis of how the WG-3 scores against the DP1s when it comes to portability, imaging, features and an overall mark.

Following is a preview of the gallery images for Pentax WG-3 and Sigma DP1s. The full galleries are viewable at Pentax WG-3 Gallery and Sigma DP1s Gallery.

For anyone who is going to travel with your camera frequently, you should factor in its weight and proportions. The Pentax WG-3 comes with outside dimensions of 124mm x 64mm x 33mm (4.9" x 2.5" x 1.3") with a weight of 230 grams (0.51 lbs) whilst the Sigma DP1s has measurements of 109mm x 60mm x 31mm (4.3" x 2.4" x 1.2") accompanied by a weight of 270 grams (0.60 lbs).

Remember that, the weight of an Interchangeable Lens Camera will differ based on the lens you are utilising at the time. Here is the front view overall size comparison of the WG-3 versus the DP1s.

Taking into account size and weight, the portability score of the WG-3 and DP1s is 90 and 90 respectively.

Generally, its hard to envision the difference in sensor dimensions merely by checking out a spec sheet. The pic here should provide you a stronger sense of the sensor sizes in the WG-3 and DP1s.

Clearly, each of the cameras posses different megapixels and different sensor dimensions. The WG-3 having a smaller sensor will make achieving shallow DOF harder and the Pentax WG-3 will produce greater detail because of its extra 11 Megapixels. Higher resolution will make it easier to crop pictures somewhat more aggressively. The fresher WG-3 is going to have a benefit with regard to sensor technology.
