This is perhaps slightly OT, but I had my 5DII in Brunei for 3 months, and had NOTHING but grief.
It never got rained on, or even damp, but the persistent high humidity did damage anyway. After a month there it stopped working and had to go back to Canon... where they replaced pretty much everything except the shutter (including the motherboard and so on)... then just before I came back it stopped working AGAIN, and they had to do the same level of repairs... everything except the shutter.
I was not even there as a photog, the camera spent 99% of the time in a locked Pelican in my 5-star hotel suite.
I had it sent straight back to me in Perth, and it had been fine ever since.
