I was at a race over the weekend and got mud all over the 7D. It got on the lens, and around the pop up flash and where the strap loop thing connects to the camera. Maybe a few other places. It wasn't covered or anything, but do you think this could really damage anything? I got it all off pretty much except possibly areas I can't get to or see.
That's the nature of a muddy woods dirtbike race though... can't avoid it too much... wasn't any other way to get the pics either.
