Pentax K-S1 vs Pentax WG-2 GPS

Below, we are contrasting the Pentax K-S1 vs Pentax WG-2 GPS, one is a Advanced DSLR and the other is a Waterproof and they are both built by Pentax. There exists a huge gap between the image resolutions of the K-S1 (20MP) and WG-2 GPS (16MP) and the K-S1 (APS-C) and WG-2 GPS (1/2.3") use totally different sensor measurements.

The K-S1 was introduced 2 years after the WG-2 GPS which is quite a significant gap as far as technology is concerned. Both the cameras come with different body type with the Pentax K-S1 being a Mid-size SLR camera and the Pentax WG-2 GPS being a Compact camera.

Before delving in to a comprehensive comparison, below is a quick introduction of how the K-S1 scores vs the WG-2 GPS when considering portability, imaging, features and an overall score.

Here is a sample of the gallery pictures for Pentax K-S1 and Pentax Optio WG-2 GPS. The whole galleries are available at Pentax K-S1 Gallery and Pentax WG-2 GPS Gallery.

When you are going to carry around your camera frequently, you're going to have to factor in its weight and dimensions.

Keep in mind, the weight of an Interchangeable Lens Camera will differ dependant on the lens you have at the time. Following is the front view overall size comparison of the K-S1 compared to the WG-2 GPS.

Considering dimensions and weight, the portability grade of the K-S1 and WG-2 GPS is 69 and 91 respectively.

Normally, it can be difficult to visualise the difference between sensor sizes purely by checking technical specs. The picture below might offer you a stronger sense of the sensor sizes in the K-S1 and WG-2 GPS.

As you can tell, both of the cameras posses different megapixel count and different sensor sizes. The K-S1 having a larger sensor will make shooting bokeh simpler and the Pentax K-S1 will give greater detail using its extra 4 Megapixels. Greater resolution can also enable you to crop photos somewhat more aggressively. The fresher K-S1 will have an advantage when it comes to sensor tech.
