Ikelite's Autoflash AF-35 is designed to replicate the auto exposure flash on a point-and-shoot camera. Just attach the tray to the bottom of the housing, load the light head with four double-As and start shooting. The Auto Flash Kit weighs only about two pounds including batteries, and is depth-rated to 300 feet. It's compact, lightweight and easy to use. As a light source for a housed point-and-shoot camera, is hard to beat.
