I have not personally used the camara bags but I have seen pics from people that have used them, The results are fairly good, however I would thing that they would be better used in shallower conditions. Though I don’t really have anything to back that statement up. Just a personal observation. Also, how do you get to the controls on the camera? again it would look like to me they would be harder to get to thru the plastic bag. These are just a few things I would be concerned about.
