It feels like this myth has been around since the beginning of photography: if you drop your equipment in salt water, you just have to soak it in fresh water.
With modern technology and the proliferation of the Internet, it would seem that the myth has been spread further afield. We're here to put an end to this myth once and for all. If you drop your equipment in salt or fresh water, it's toast. It's over, gone, finito. Use it for a paper weight. Or perhaps a door stop. And while we are myth busting, don't put your iphone in the microwave to charge it either.
In conclusion, don't put your camera equipment in salt or fresh water - every, unless it is waterproof. End of discussion. How many ways can we beat that dead horse?
