First weekend out with the T2i and kit lens was a boat trip. Camera was totally submersed in an unseen wave - water in the battery box, mist behind the viewfinder, and a clouded LED screen on the back. I figured it was cooked so I took the lens off, battery out, and left the whole pile of soaked plastic on the end of the dock while I went in for lunch and boat fuel. Return two hours later, noted that the signed of internal vapor were gone, and decided to put humpty back together again. Everything Worked! And has quite well to this day!
That was two years ago. It woudl be fun to see how to determine the frame count of the body since that day, I bet its tens of thousands.
