Pentax WG-10 vs Ricoh GR III Sensor Comparison

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.
