Having a water proof camera is a great idea for those who travel, or spend time on the water. Customers can choose from the five best waterproof cameras, under $300. The first is the Samsung AQ100, followed by the Pentax Optio W90, Canon PowerShot D10, Sony Cyber-shot DSC-TX5, Panasonic Lumix DMC-TS2.
