Hey ~tat8112, i too love taking photos underwater, but i must confess i do not have the money for top photography gear that brings best results for underwater atmosphere. So when i went on a live-aboard dive trip in 2007 i opted to buy a FujiFilm F10 small digital camera from Ebay really cheap, b/c i had seen a underwater case specifically designed for it: the FinePix Waterproof Case WP-FXF10. i did not pay too much for the bundle, but trust me when i say, there are far greater cameras and cases that have been produced since then. Olympus does a lot of underwater stuff and Ikelite works with a lot of underwater systems (can work for most cameras), and if you go to dive shops, they have a lot of great advice (it really depends on what you want to photograph - underwater cameras now have special features called 'shark shack' that help you keep a steady and clear photo). Hope that helped. If i had the money, i'd buy a Nikon D70 or Canon and then get an Ikelite case. Good luck, and sorry about you shark pics. i hate it when that happens
