1. It looks as if it will be a lot harder to actually change any settings or control your camera with that kind of bag. But it is cheap compare to those better brands like Sea & Sea which is targeted at profesional mostly... cost 30x more. I'll still have my doubt. If it leaks, your hundreds of dollars of camera gears are all gone...
