Pentax X90 vs Ricoh GR III Sensor Comparison

As you can plainly see, each of these cameras have different megapixel count and different sensor sizes. The X90 because of its tinier sensor is going to make achieving shallow DOF tougher and the Ricoh GR III will offer extra detail as a result of its extra 12 Megapixels. Higher resolution will make it easier to crop pictures a bit more aggressively. The more aged X90 is going to be disadvantaged in sensor tech.
