saw that and the freezer test, but I never done anything close to that to my 7D or my 5D ..
I know they can do a lot - IF - you are lucky but with the e3, e5 it was a regular thing.. and it was still shiny and perfect unlike the burned and freezed cams from drtv..
I never had the courage to wash my 7D and risk the warranty, but with my e3 I knew it can handle it...
I've never submerged and frozen my 7D, however I have used it in some pretty extreme weather. This April 2012, I spent more than eight hours one day at Chatfield State Park here in Colorado. On that one day, it rained profusely, sleeted, snowed a couple times, and at a couple points it even hailed dime-sized hail. I had my camera out, soaking wet, photographing birds the entire time. You can read about that on my blog. The featured photo shows a torrential mix of sleet and rain from that day. Both my 7D, and my 100-400mm L lens, were drenched for most of the day, and didn't skip a beat. Never had any fogging or anything like that, either on that day or any day since.
