Back in 2010 I purchased a really inexpensive camera bag that is designed to protect your gear against basic exposure to water. The reason I wanted this was to take my 50d with me in my kayak. In the end it was kind of a difficult thing to work with, and I seldom use it. GoPro kind of makes it pointless anyway! 😉
I did end taking a few shots that turned out ok, and I particularly like this one.
