Smartphones don't really work for underwater photography. Even the water resistant models have very limited depth ratings so to take them scuba diving you need a strong housing, just as with any other camera. There are underwater housings available for a few smartphone models but controlling anything through the touch screen is problematic, the small lenses and sensors don't work well in dim light, and there isn't a good way to trigger external strobes.

Any thoughts on the various action cameras for underwater? I've got an inexpensive (not GoPro) one that I've taken diving. It's just in looping video mode, cutting a new clip every few minutes, and could certainly use additional lighting. If I want stills, I just grab them from a freeze frame.

While I'm starting to get more into diving, I don't want to just throw money at other goodies before I know what they'll do for me.
