My D800 experience
I used mainly the Nikon 500mm Vr2. Some of the photos were handheld i.e. #7. The remainder a combination of bean bags or just bracing the lens on the vehicle seat etc. I also used the 70-200 and found that lens to be stellar on the D800E, however the focal length is not ideal on Safari.
