Pentax XG-1 vs Ricoh GR III

Its time to take a deeper look at the Pentax XG-1 and Ricoh GR III, one is a Small Sensor Superzoom and the other is a Large Sensor Compact by brands Pentax and Ricoh. There exists a huge gap between the resolutions of the XG-1 (16MP) and GR III (24MP) and the XG-1 (1/2.3") and GR III (APS-C) feature totally different sensor sizes.

The XG-1 was brought out 5 years earlier than the GR III which is quite a significant gap as far as technology is concerned. The two cameras offer different body type with the Pentax XG-1 being a SLR-like (bridge) camera and the Ricoh GR III being a Large Sensor Compact camera.

Before diving through a more detailed comparison, below is a simple introduction of how the XG-1 matches up versus the GR III in relation to portability, imaging, features and an overall score.

Here is a sample of the gallery pictures for Pentax XG-1 and Ricoh GR III. The entire galleries are viewable at Pentax XG-1 Gallery and Ricoh GR III Gallery.

For anybody who is aiming to carry around your camera regularly, you need to factor its weight and measurements. The Pentax XG-1 comes with outside measurements of 119mm x 89mm x 98mm (4.7" x 3.5" x 3.9") having a weight of 567 grams (1.25 lbs) while the Ricoh GR III has proportions of 109mm x 62mm x 33mm (4.3" x 2.4" x 1.3") along with a weight of 257 grams (0.57 lbs).

Take into account, the weight of an Interchangeable Lens Camera will change dependant on the lens you are utilising at that time. Following is the front view dimensions comparison of the XG-1 versus the GR III.

Taking into account dimensions and weight, the portability rating of the XG-1 and GR III is 66 and 90 respectively.

Quite often, it is tough to see the gap between sensor sizes purely by reading technical specs. The pic below may offer you a stronger sense of the sensor sizing in the XG-1 and GR III.

As you have seen, each of these cameras offer different megapixel count and different sensor sizes. The XG-1 due to its tinier sensor will make achieving shallower depth of field tougher and the Ricoh GR III will offer greater detail having its extra 8MP. Greater resolution can also make it easier to crop photos a little more aggressively. The more aged XG-1 is going to be behind when it comes to sensor tech.
