Hey All, My parents have asked me for a recommendation of two different waterproof cameras. One is the Olympus TG series (probably looking at a TG-1 from KEH), the other is the Panasonic TS4. They are going on a cruise, and want something while snorkeling. Mom doesn't dive, and Dad can't anymore due to medical, so snorkeling depth is the farthest they will go. They are not photo enthusiasts, so something that has a "set and forget" mode would be great (not sure if these sport the iAuto?). They dont have any need for wireless, so that is why the newer TG's aren't really as much of an option vs. price savings. Any comments?
