In reply to GerM:
My Fuji finepix finally gave up the ghost this year after a good 18 months of abuse, recording coasteering at work, so submerged in saltwater alot of the time. I,ve replaced it with a Pentax WG10 which has much better picture quality and I've also been using it to freedive with down to about 10m so I am well impressed so far.
Worth taking the time after using it in the sea to soak what ever camera in fresh water. I known a few people who have issues with salt crystals building up in the buttons and any camera which has an automatic sliding lense cover doesn't seem to last very long.
Hope that helps!
