As you can see, both of the cameras feature the identical sensor size albeit not the same megapixels. You should count on the Ricoh G900 to provide you with more detail with its extra 4MP. Higher resolution will let you crop shots way more aggressively. The more aged WG-3 GPS will be behind in sensor innovation.
