The WG-3 was brought out 3 years earlier than the Quattro which is quite a significant gap as far as technology is concerned. Each of these cameras come with different body type with the Pentax WG-3 being a Compact camera and the Sigma Quattro being a Rangefinder-style mirrorless camera.

Before getting straight into a step-by-step comparison, below is a quick view of how the WG-3 grades against the Quattro in terms of portability, imaging, features and an overall mark.

Below is a sample of the gallery pics for Pentax WG-3 and Sigma sd Quattro. The entire galleries are provided at Pentax WG-3 Gallery and Sigma Quattro Gallery.

Quite often, it can be tough to picture the difference between sensor dimensions purely by looking at technical specs. The picture underneath will provide you a more clear sense of the sensor dimensions in the WG-3 and Quattro.

As you can tell, both the cameras posses different megapixel count and different sensor dimensions. The WG-3 because of its tinier sensor is going to make getting shallower DOF more challenging and the Sigma Quattro will give you greater detail having its extra 13 Megapixels. Greater resolution will also help you crop photos somewhat more aggressively. The more aged WG-3 is going to be disadvantaged with regard to sensor tech.
