Pentax WG-10 vs Ricoh GR III

Below is a extended comparison of the Pentax WG-10 and Ricoh GR III, former being a Waterproof while the latter is a Large Sensor Compact by companies Pentax and Ricoh. There is a large difference among the resolutions of the WG-10 (14MP) and GR III (24MP) and the WG-10 (1/2.3") and GR III (APS-C) use totally different sensor measurements.

The WG-10 was announced 6 years before the GR III and that is a fairly serious difference as far as camera tech is concerned. Both of the cameras offer different body type with the Pentax WG-10 being a Compact camera and the Ricoh GR III being a Large Sensor Compact camera.

Before we go through a full comparison, below is a short summary of how the WG-10 matches up versus the GR III when it comes to portability, imaging, features and an overall grade.

Here is a preview of the gallery photos for Pentax WG-10 & Ricoh GR III. The whole galleries are viewable at Pentax WG-10 Gallery & Ricoh GR III Gallery.

When you are intending to lug around your camera often, you'll need to consider its weight and size.

Don't forget, the weight of an ILC will vary depending on the lens you have at the time. Underneath is the front view over all size comparison of the WG-10 compared to the GR III.

Using size and weight, the portability score of the WG-10 and GR III is 93 and 90 respectively.

Often, it is hard to visualise the contrast in sensor measurements purely by viewing specifications. The visual below should offer you a greater sense of the sensor sizes in the WG-10 and GR III.

To sum up, both of the cameras enjoy different megapixel count and different sensor measurements. The WG-10 with its smaller sensor will make getting shallower depth of field harder and the Ricoh GR III will result in greater detail with its extra 10MP. Higher resolution will enable you to crop shots far more aggressively. The older WG-10 will be disadvantaged with regard to sensor innovation.
