The K-S1 was unveiled 2 years after the WG-2 which is quite a sizable gap as far as tech is concerned. Both the cameras offer different body type with the Pentax K-S1 being a Mid-size SLR camera and the Pentax WG-2 being a Compact camera.

Before going through a in-depth comparison, below is a simple highlight of how the K-S1 grades versus the WG-2 with respect to portability, imaging, features and an overall mark.

Below is a preview of the gallery images for Pentax K-S1 and Pentax Optio WG-2. The full galleries are available at Pentax K-S1 Gallery and Pentax WG-2 Gallery.

If you are going to travel with your camera, you will need to consider its weight and measurements.

Keep in mind, the weight of an Interchangeable Lens Camera will vary depending on the lens you are using at that time. The following is the front view dimension comparison of the K-S1 and the WG-2.

Factoring in size and weight, the portability score of the K-S1 and WG-2 is 69 and 91 respectively.

Generally, it is very difficult to envision the contrast between sensor dimensions merely by looking at specs. The image below may provide you a clearer sense of the sensor dimensions in the K-S1 and WG-2.

As you can plainly see, both cameras enjoy different resolutions and different sensor dimensions. The K-S1 having a bigger sensor will make achieving bokeh simpler and the Pentax K-S1 will resolve extra detail having an extra 4MP. Higher resolution will also make it easier to crop photographs far more aggressively. The younger K-S1 will have an edge when it comes to sensor innovation.
