Pentax XG-1 vs Ricoh GR Digital III Sensor Comparison

Generally, its difficult to visualise the contrast in sensor sizing only by looking through technical specs. The graphic underneath will offer you a much better sense of the sensor measurements in the XG-1 and GR Digital III.

As you have seen, the two cameras offer different megapixel count and different sensor sizing. The XG-1 having a smaller sensor will make getting shallower depth of field more difficult and the Pentax XG-1 will render greater detail with its extra 6 Megapixels. Higher resolution will allow you to crop pictures a little more aggressively. The more modern XG-1 is going to have a benefit with regard to sensor tech.
