OK, that makes sense...sorry for the misperception on my end.
I keep a "normal sized" lens on the D800's (so the cameras are ready to shoot), and the cameras sit face down in Lowe Pro Toploader AW padded cases, with those residing in a metal file cabinet drawer. The padding will cushion the severe vibration possible in an earthquake (like the jagged, rough ride we had in the 1994 Northridge quake), and the metal cabinet will survive a partial collapse of the building.
