To sum up, both of those cameras enjoy different resolutions and different sensor dimensions. The WG-4 having a tinier sensor is going to make shooting shallower depth of field harder and the Ricoh WG-4 will deliver greater detail with its extra 13 Megapixels. Greater resolution will make it easier to crop images far more aggressively. The younger WG-4 should have an edge with regard to sensor tech.
