Good day gents (and ladies), anyone here could recommend a good (and cheap) camera rain cover? I know some brands like Op Tech, Kata and Think Tank Photo had one, but I'm looking for something much tougher that can secure my camera from all sides. I will be traveling next month and taking pictures of water caves and seascapes. I don't think splashes of water will be the main problem, but the water itself. I'll be traveling by the use of small boats so seawater will be everywhere. I need some kind of zip pouch, that would atleast cover the camera up to 10ft (deeper is better). I don't have enough cash for hard cases, and they would be extremely heavy for me to carry all day long. Any recommendations or DUIs?
