Update a few months later: I have several times used the bag while snorkeling and she was close. One makes sure though always a few thoughts as to whether it considers real, but it has maintained and there are great photos were taken. (If you do not zooms sees something the edge of the lens attachment as a black circle, but I think that now is not so bad.) It is not easy through the film and the goggles to see the screen, but with a digital camera one can easily take lots of photos in the right direction and then select the best.
Conclusion: Good, cheap substitute for a real underwater housing, which absolutely reaches for a couple of photos.
