well, i purchased this camera on a whim. it's water proof to 30 feet, and i was having trouble getting decent pics from the waters surface, especially shooting the lps which is amost always on the sand bed (25" away from the camera), so i figured a submersible camera might be just the trick.
it turns out i was correct. i love this thing. the only trouble i was having with it was keeping my jittery hands still while attempting macros. the following pictures were taken in under a minute, with no tripod and one hand, on the full automatic setting-
this camera has settings like "aquarium" and a zillion others i didn't even get into yet. i'm very happy with it so far!
