I bought a Canon G12 with an underwater casing a few years ago and enjoy taking shots with it.
However, I think it may be time to consider taking my 5D underwater (although the price tag is not for the faint of heart).
A few underwater favorites from Palau. Off of the beach of our hotel was a marine sanctuary and the biggest clams I have ever seen. This one was more than 1m long and if you got to close, it would snap shut.
I had never seen a blue starfish before. They were everywhere.
Hang on little starfish.
Come to think of it I had never seen a neon blue and pink clam before either.
This fellow was tucked in the coral and looked rather ominous.
The other thing that I noticed was that many clams were literally embedded into the coral, like these two. One has to wonder how many years that took?
Coral as far as you could see.
Note the sharp looking teeth on this cheery pink fellow.
Spot the fish.
Last shot, the rain from below.
