Hi,
I am not sure if camera animation can be exported directly from Max, however I know at least one trick to make it work.
In Max create either an object or a bone, that is constrained to your camera. Export this either as a chr and caf, or as a cga. In Sandbox, bring in this chr or cga into TrackView, play the animatin, and attach the camera to it (I would recommend using charAttachHelper)
