Pentax WG-2 GPS vs Sony QX100

Below is a thorough assessment of the Pentax WG-2 GPS vs Sony QX100, one being a Waterproof and the latter is a Lens-style by manufacturers Pentax and Sony. The image resolution of the WG-2 GPS (16MP) and the QX100 (20MP) is relatively close but the WG-2 GPS (1/2.3") and QX100 (1") come with totally different sensor measurements.

The WG-2 GPS was brought out 19 months prior to the QX100 which makes the cameras a generation apart from each other. Both the cameras offer different body type with the Pentax WG-2 GPS being a Compact camera and the Sony QX100 being a Lens-style camera.

Before we go through a complete comparison, below is a brief view of how the WG-2 GPS grades against the QX100 in the way of portability, imaging, features and an overall grade.

When you are intending to lug around your camera often, you're going to have to think about its weight and volume. The Pentax WG-2 GPS offers exterior measurements of 122mm x 61mm x 30mm (4.8" x 2.4" x 1.2") accompanied by a weight of 198 grams (0.44 lbs) whilst the Sony QX100 has sizing of 63mm x 63mm x 56mm (2.5" x 2.5" x 2.2") accompanied by a weight of 179 grams (0.39 lbs).

Remember that, the weight of an Interchangeable Lens Camera will change dependant on the lens you have chosen at that moment. Following is the front view physical size comparison of the WG-2 GPS and the QX100.

Factoring in size and weight, the portability rating of the WG-2 GPS and QX100 is 91 and 92 respectively.

Usually, it is very hard to see the gap in sensor measurements just by looking through a spec sheet. The graphic here may give you a far better sense of the sensor measurements in the WG-2 GPS and QX100.

Clearly, both of these cameras offer different resolutions and different sensor measurements. The WG-2 GPS featuring a smaller sensor will make getting shallow DOF tougher and the Sony QX100 will render more detail having its extra 4MP. Higher resolution can also make it easier to crop pictures a little more aggressively. The older WG-2 GPS will be disadvantaged with regard to sensor innovation.
