thanks for sharing this.
now this is worrying me. I do shoot a lot in heavy rain previously with my 6D and it survived pretty decently. There was only once that I was out shooting continuously in rain for more than 2 hours and it started to to behave weirdly. But left it overnight in room with radiator and it worked fine next the day.

I thought this should be better than my old 6D but now doesn't seem so.
