Pentax XG-1 vs Ricoh GR III Sensor Comparison

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.
