Pentax WG-2 GPS vs Sony RX10 III

Below is a extensive comparison of the Pentax WG-2 GPS versus Sony RX10 III, one being a Waterproof and the other is a Large Sensor Superzoom by competitors Pentax and Sony. The image resolution of the WG-2 GPS (16MP) and the RX10 III (20MP) is very similar but the WG-2 GPS (1/2.3") and RX10 III (1") use different sensor measurements.

The WG-2 GPS was introduced 5 years prior to the RX10 III and that is quite a large gap as far as technology is concerned. Each of the cameras offer different body type with the Pentax WG-2 GPS being a Compact camera and the Sony RX10 III being a SLR-like (bridge) camera.

Before diving through a thorough comparison, below is a brief overview of how the WG-2 GPS grades vs the RX10 III when considering portability, imaging, features and an overall grade.

Here is a sample of the gallery pics for Pentax Optio WG-2 GPS and Sony Cyber-shot DSC-RX10 III. The whole galleries are viewable at Pentax WG-2 GPS Gallery and Sony RX10 III Gallery.

In case you're looking to lug around your camera, you are going to need to factor in its weight and volume. The Pentax WG-2 GPS comes with outer dimensions of 122mm x 61mm x 30mm (4.8" x 2.4" x 1.2") and a weight of 198 grams (0.44 lbs) while the Sony RX10 III has sizing of 133mm x 94mm x 127mm (5.2" x 3.7" x 5.0") along with a weight of 1051 grams (2.32 lbs).

Do not forget, the weight of an Interchangeable Lens Camera will change based on the lens you use at the time. Underneath is the front view dimensions comparison of the WG-2 GPS compared to the RX10 III.

Factoring in dimensions and weight, the portability grade of the WG-2 GPS and RX10 III is 91 and 53 respectively.

Typically, it is very hard to picture the gap between sensor measurements only by reviewing a spec sheet. The photograph here might give you a far better sense of the sensor sizes in the WG-2 GPS and RX10 III.

As you can see, both of these cameras offer different resolutions and different sensor measurements. The WG-2 GPS having a tinier sensor is going to make getting shallow DOF more challenging and the Sony RX10 III will offer more detail using its extra 4 Megapixels. Greater resolution will also make it easier to crop photos a little more aggressively. The older WG-2 GPS is going to be disadvantaged with regard to sensor tech.
