Here is another stocking stuffer under $30…a Lens Coat Lens Sack. This is a simple version of a bean bag support. You fill it up with rice, beans or similar, hang it over your car window opening or the bar of your safari vehicle, and you are ready to go. There are fancier versions for sure with are larger and a little better for really big lenses. But in Africa I was using a simple Lens Coat Lens Sack and it worked just fine. The sack has sticky rubber on the underside to help it grip the door. Simple and it works.
