I wasn't actually going to post this, but after reading the sad "my 5d mkiii is dead" story (http://www.canonrumors.com/forum/index.php?topic=16121.0
) I'm going to...
I was at altitude with my 5d MKIII over the weekeend, looking for tigers (with no success, great birding though). It was a lot cooler compared to lower-down, and humid as we were in the cloud layer. I got some mist and light rain on my camera, but nothing major. As we came down the hills, temp increased dramatically. On the descent i pulled out my camera to take a shot and noticed it was a completely misted photo! I had condensation INSIDE my camera! I had changed lenses a couple of times, but not when it was wet/misty and always indoors, but that does not affect atmospheric humidity. We were in a car when i noticed the condensation, so immediately removed the battery, took off my lens and let the camera "dry" for a couple of mins. When I tried it again a few minutes later, It seemed fine.
This happened to anyone else? Should i be worried?
FYI - I live in Bangalore, India, and it is monsoon season, so to be honest, unless I don't change lens this whole season, there is always high humidity and temperature changes!
