Pentax WG-2 GPS vs Sony HX99

Below is a detailed review of the Pentax WG-2 GPS and Sony HX99, one being a Waterproof and the other is a Small Sensor Superzoom by companies Pentax and Sony. The sensor resolution of the WG-2 GPS (16MP) and the HX99 (18MP) is very close but the WG-2 GPS (1/2.3") and HX99 (1/2.3-inch) provide different sensor sizing.

The WG-2 GPS was introduced 7 years before the HX99 and that is a fairly large gap as far as camera tech is concerned. Each of these cameras have the same body design (Compact).

Before we go into a in-depth comparison, here is a simple introduction of how the WG-2 GPS scores versus the HX99 in the way of portability, imaging, features and an overall grade.

Remember, the weight of an Interchangeable Lens Camera will differ depending on the lens you are working with at the time. Underneath is a front view measurement comparison of the WG-2 GPS compared to the HX99.

Using size and weight, the portability grade of the WG-2 GPS and HX99 is 91 and 91 respectively.

Usually, it is very tough to visualize the gap in sensor measurements merely by researching specs. The graphic below may offer you a stronger sense of the sensor measurements in the WG-2 GPS and HX99.

All in all, the 2 cameras have different resolutions and different sensor measurements. The WG-2 GPS having a larger sensor is going to make getting shallower DOF easier and the Sony HX99 will render more detail using its extra 2 Megapixels. Greater resolution will help you crop photos a bit more aggressively. The older WG-2 GPS will be disadvantaged with regard to sensor technology.
