Everything else seems to work as normal, and in particular the exposure meter works fine in liveview mode.

What specifically do you mean? Is the metering merely inaccurate? Severely over or under exposed?

Metering in live view is accomplished by the image data read directly from the sensor. Metering in TTL is does through a small sensor located approximately above the view finder above and behind the pentaprism. So water entering around the eye piece could have created a problem, but as the sensor is a sealed IC package, I have a hard time believing that this did not dry out which would restore function. Just condensation should not cause permanent damage, IMO.

Interesting.  I still haven't heard anything from the repair people, but must admit that I'm tending to the theory that water came via the DA16-85.  In any case, the answer to your first question is that the exposure meter is completely toasted --- pretty much independently of the amount of light, it sets exposure a the 30 second maximum.  Which was very confusing at first because it seemed instead that the shutter had malfunctioned (the shutter would open and I'd give up well before it closed).

Happiness,

Andrew
