Ricoh acquired the Pentax brand more than two years ago, but you almost wouldn't know it when the badging has largely remained the same. However, that's changing today -- Ricoh's new WG-4, WG-4 GPS and WG-20 compact cameras are its first to ditch the Pentax name. From now on, you'll only find the label on interchangeable lens cameras and their accessories. These rugged point-and-shoots haven't seen dramatic changes beyond the corporate logo, mind you. The WG-4 and its GPS-equipped variant add user-programmable and shutter priority modes to the WG-3's basic formula, which includes a 16-megapixel sensor, a 4x lens and a body that's waterproof to 45 feet. The WG-20 (shown below) is very similar to the WG-10, sharing its 14-megapixel sensor, 5x lens and 33-foot waterproofing. All the new models ship in March; the WG-20 will be available for $200, while the WG-4 and WG-4 GPS will respectively cost you $330 and $380.
