The Acratech Video Adapter with Arca-Style Clamp allows you to use an Arca Swiss-compatible quick-release plate (from manufacturers such as Acratech, Kirk, Arca-Swiss, R.R.S. and many others) on your DSLR camera and mount the assembly to a dedicated video head. With both 1/4"-20 and 3/8"-16 threads, the Video Adapter fits any standard video head.
The adapter is 2.4" long and holds over 25 lb., to support nearly any video DSLR setup imaginable. A detent pin prevents Arca-style plates from accidentally sliding out of the clamp. A large 0.6" spirit level ensures that your video will be flush with the horizon.
