If you are looking for a camera to take coral pics, I recently bought this one, and am quite happy with it now. It can take pics underwater really close up, with up to an f2.0 aperture setting. The only negative I found was that it did not have a manual focus setting, although the auto focus does work really well.
Here is a link when I was figuring out the WB for LEDs.
