At depth 

In Casio Exilim EX-Z75 and EWC-10 underwater case

First, below about 4-5 feet, the pressure will seal all but the most busted cases. Second, below about 30 feet you'll almost certainly need a flash. And below about 75 feet you'll need an external flash. Thirdly, NO VIEWFINDER? Using an optical viewfinder really steadys the hand. This is a well established fact.
