Paul,
Actually, a couple of us had rain protection for our camera/lenses. If you look on my list of gear in the Intro section you will see I had the Kata E702 and the E704. The E702 protects the camera body and a amall lens and the E704 attaches to protect longer lenses (i.e. the 200-400 VR). It turned out we had absolutely fantastic weather, so like some other items I took along, they never got used. The weather during our stay was phenomenal, ranging from low 60's to mid 70's the entire time.
