The Steadybag Junior from Visual Departures allows fast, rock-solid shooting on any surface, eliminating time-consuming tripod setup.  It conforms to any uneven surface bringing a new freedom to location still and video photography.  Steadybag is filled with custom-milled polypropylene beads in an outer casing made of rugged waterproof expedition-grade nylon, and it comes with a padded shoulder strap.

If you use the Arca-Swiss type system of quick release camera and/or lens plates (from Acratech, Arca-Swiss, Foba, Novoflex or Wimberley) and seek the ultimate stability upon a beanbag, you'll find it by attaching two Wimberley Module 1 quick release arms (B&H item code "WIM1") to the quick release plate.  Connected to the quick release plate so that the arms face in opposite directions, a snowshoe-like foot is created which makes switching the camera from horizontal/vertical within the lens collar a cinch.
