My hand is up for replacing rubber seals and O rings, and air leaks too in
pressure hoses, though water is a lot thicker than air.
I've been thinking about getting one of those camera bags for the E-500,
though it doesn't fog up inside the lens on a cold damp day (my breath just
clouds the eye piece and my glasses when I'm trying to shoot, so I can't see
to shoot)
The C-5050 of mine, we;;, I was sure I'd lost that 3-4 times due to rain,
twice it got wet so fast I popped the batteries right out and tossed it in
the driest place I could find in my pack.....but the worst I have
experienced was that moisture gets easily into the Wide angle/Macro I have
on the lens adaptor. What kind of grease/oil could I use to keep that from
leaking as rapidly as a water fall?

Michael isn't the deepest analytical thinker, and his casual attribution
of the C failures to simple statistics doesn't really hold up. The
proportion idea is too simple. There's not enough data here to say for
sure, but I suggest further possible explanations.
- I would bet that age and use are at the bottom of the 1D(s) failures.
Anybody who hasn't had to replace o-rings in faucets, valves, hose
reels, etc. etc., please hold up your hand. Hmmm, no takers. Weather
sealing of these cameras depends heavily on o-rings. These are cameras
used mostly by pros and others who use them heavily.
O-rings in places that move, like zoom rings, lens mounts, etc. get
worn. Their sealing abilities decline with age and use. Cold puts extra
strain on the material on the rings, making them less elastic, so leaks
at the flat spots are even more likely.
The average age of the D200s will turn out to be much less than the pro
D1(s)s, simply because they are a much newer camera. Likewise, they will
have taken many fewer frames, on average. AT a guess, they will more
likely belong to amateurs who simply use them less heavily than the pros
with 1D(s)s.
How many think any of the 1D(s) users who experienced failures lubed
their mount o-rings for the trip, et along had the umpteen frame O-ring
replacement service?
Anybody who doesn't expect more failures from a car with 10,000 miles on
the clock than one with 200,000?
- The 5D and XTis need no explanation. They are not intended for use in
the rain and clearly say so. So now those who didn't believe the specs
and instructions now know they were wrong. I don't work well in the
rain, so I think my 300D and 5D are safe.

Plastic bags and rubber bands in the camera bag. Lens goes through hole
made in bag. Rubber band holds bag on lens. Hands work camera inside
bag. Not rocket science, doesn't cost anything. Hassle if front of lens
rotates, but guess what, most AF lenses don't.
