Ricoh G900 vs Ricoh GR III Sensor Comparison

Normally, its tough to see the contrast between sensor dimensions just by reading technical specs. The picture here should give you a more clear sense of the sensor measurements in the G900 and GR III.

As you can tell, both of these cameras offer different megapixel count and different sensor dimensions. The G900 featuring a tinier sensor will make shooting bokeh trickier and the Ricoh GR III will deliver more detail as a result of its extra 4MP. Higher resolution can also make it easier to crop photographs a little more aggressively. The more aged G900 is going to be disadvantaged in sensor innovation.
