I will see what I can do and send some your way. I have yet to take the D4 to the desert areas, but my Leica's have been in those environs, both have even been dropped a few times with no problems. Just lucky I guess. If all goes well the D4 is headed to the southwest later this year for a desert trial. I will have to admit the Sinai, Negev, and Sahara are some pretty extreme environments.
