The lens hood on the 24-70mm, 200-400mm and all of the super telephoto lenses are quite deep and protect the front element from rain quite well. The Hydrophobia has velcro straps that can be tightened around the lens hood protecting the full lenth of the lens and then some. On the 24-70mm and 70-200mm one can use a Nikon NC or other brand of clear filter for a little extra protection. As long as the wind isn't driving the rain into the lens, the front element is reasonably protected. When not shooting, it is good prectice to keep the lens pointed down and to protect the front of the lens from the wind as much as possible. Keeping a few microfiber towels and a lens cloth is always a good idea.
