Even with gale-force winds on the beach with nasty saltwater spray has been sprinkled only the front lens. Without this we would have diverse Capes great shots can never make. The film is relatively thick, so it has not yet received any leak, although we have used about 5 times and 2 weeks brought with them crumpled in a backpack (evenings always out to dry).
Yes it is a bit big, but that does this more quickly to be able to put it over the camera. The extra compartment for lightning does not hurt if no one is mounted. Only 2 pictures it has me destroyed due storm, as the cord which is lashed to the lens flew before the image - but this is my fault.
I order the same even 2, that I will pass on my second camera in the next holiday with my travel companions.
