I know it's overkill, but I have Nikonos V that I take to the beach or boating or backpacking. Any time that I might be in camera-destroying situations. On the beach, I don't have to worry about sand and it can go right into the water with me. I put a deep lenshood on it to keep raindrops off the lens and shooting even in a driving rainstorm is not a problem. That 35mm 2.8 delivers beautiful results.
