Howdy all - my first post. I am planning a move to Maui and really looking forward to some underwater snaps - which I have never done. I shoot with a Sony A700 and am looking at getting the Ikelite housing. Anybody have any experience with the product? Will it house any size lens? Also is there any particular filters I should look into for shooting underwater? Scared out of my mind to dunk the camera under water - any advice on insurance would be appreciated as well. CAN'T WAIT!!
