I am thinking if the flight is that rough I want off and to hell with the gear!!!!As the others have said, it's not a problem. I always carry my camera/lenses on the plane with me, rather than pack it in the luggage. Before my last trip to Europe, a salesman at a camera store advised separating the lens from the camera. She said the constant vibration/bumps from the plane could put stress on the mount if the lens was attached to the camera. Any thoughts about that?
