UPDATE, 7D and 400mm/5.6L survived to water damage!
Yesterday my 7D was not working, so i left it on my kitchen table (i have air conditioning in my house)and tonight when i came from work i looked at it and the VF has virtually no more fog, so i put a battery in it and it worked !!! I put a CF card and took some shots … WOW!
I don’t know how long it will work but i have more hope now.
So i put the battery and CF card that were in the camera when they fell in the water to test them, here are the test shots and a short video:
