A few minutes after taking this shot I almost lost my photography gear. I was shooting with Canon 5D MK II but also had Canon 50D with a 10-22 lens with me. As a bag was rather heavy I put it on the ground in a safe place. Well, at least I thought it was safe... As you see from the above photo the sea was rather rough. Out of a sudden pretty huge wave came in. I grabbed my tripod with 5D on it and ran back. Unfortunately I didn't make my way to the bag as the wave was faster. I was a bit wet but the bag with my Canon 50D was moved by a meter or so. Fortunately for me it really turned out to be weather- and waterproof :) not a single drop got inside. But the conclusion is that if you consider leaving part of your equipment when shooting near the sea, make sure that it is really safe.
