Sometimes, its difficult to visualise the difference in sensor measurements only by viewing a spec sheet. The graphic here may provide you a more clear sense of the sensor sizing in the EX-H20G and GR III.
Clearly, the 2 cameras come with different resolutions and different sensor measurements. The EX-H20G with its smaller sensor will make achieving shallower DOF harder and the Ricoh GR III will render extra detail because of its extra 10 Megapixels. Greater resolution will also allow you to crop pics a good deal more aggressively. The older EX-H20G will be behind in sensor tech.
