I have a GH2 and will be headed out on our boat for a week long cruise ina couple of weeks. I'm always nervous about taking the camera in our dinghy as there is chance it could get wet with seawater. I was considering just a plain plastic waterproof pouch to carry it in until it was safe to remove and use it. But in looking for this I came across the line of waterproof pouches from DiCAPac that are not only waterproof but allow you use the camera while it is in the pouch. This would be ideal for situations where you might actualy be standing in water or near breaking wave. (They claim you can snorkle with it - seems risky.) Several sizes of these pouches are available, but the G series is kind of between the zoom point and shoot cameras and the full DSLR size cameras. I have the the 14-140 lens. Does anyone have experience with these? Can you comment on what size works best and how well they operate?
