I have used this bag while snorkeling in the clear waters. A star, there is that the bag is really waterproof. Otherwise, unfortunately all the pictures are out of focus, blurred, distorted and blurry because the plastic front of the lens is not smooth and (probably due to production) streaks in the material aufweißt. A fixed Kunsstoffscheibe would be much more useful here. What good is a waterproof camera bag if you can not make a good photo with it.
