The ARRI VEB-3 is a robust telescoping bracket designed to position electronic viewfinders at the rear of the camera for a comfortable operating position when working on a tripod.
Has a mount to use eye-piece levelers, and a hinged stopper arm to either stop the bracket swinging down if you dont have an eyepeice leveler.

Requires using ARRI PCA and or PCA-style blackets both on the Camera and EVF side.
