Hmmm, that picture doesn't give me much confidence in Canon's 6D weather sealing claim.....
My 6D acted erratic when I was shooting a football game under the rain. I couldn't preview the preview button activated live-view, and couldn't change my ISO.
Thankfully, after drying it for a few hours, it started working normally.
My conclusion is that the 6D isn't well weather-sealed. The rain was mostly light to moderate, but it was continuous.
My 5dmk3 behaved like that once after heavy rain. Back to normal after several hours with lots of desiccant bags around the camera to absorb the moisture. I suppose you could argue that the same weather condition could have killed any other cameras. But i was worried and upset that i couldn't use my mk3. Fortunately had a backup camera with me at the time. So don't feel bad. Happens to cameras that are supposedly better sealed too.
