Just read this on PetaPixel:http://petapixel.com/2016/02/05/shooting-a-winter-storm-killed-my-canon-7d/#more-202201
I don't understand how anyone can be so incredibly stupid. This misconception has been hashed out many times before: "weather-sealed" does not mean that you can let ocean waves hit your camera. Salt water is not rain and it is not weather.
And then, the other mistake is to think that all L lenses are "weather-sealed." Anyone who has owned an 85/1.2L knows that's not true.
To make it even worse, going back and rinsing the body and lens when salt ingress has already occurred, in the misguided belief that (1) tap water doesn't have any dissolved minerals itself; and (2) you can get enough water into the components to rinse away the corrosion?
Finally, sticking the whole thing in bags of rice? WHY do photographers spread around these stupid hacks? A large canister of silica gel put in an airtight, evacuated container with the camera, taking it out and heating it to 325 F to recharge it every 24 hours, will absorb more moisture more quickly than rice.
The repeated implications that his 1D2 survived just fine, therefore the 7D must have inferior sealing, is also galling. The 7D isn't a pro body and it's not expected to have the kind of sealing that a 1-series body needs, but that doesn't mean that it's not "weather-sealed." It just means that Canon sees fit to provide in their flagship bodies a level of sealing that goes above and beyond that needed to guard against damage from typical adverse weather, given the cost and the target market (pro shooters).
Part of the thing that irritates me as a photographer is how personal anecdotes and bad advice get passed around as if they were gospel truth. This guy got exactly what he deserved for his ignorance and misinformation.
