Zeiss ND Lens Gear Medium

Turn your camera lenses into movie lenses with the ND Lens Gear Medium from Zeiss. No additional tools required, this geared, aluminium ring simply slides onto any lens measuring 78 84mm in diameter to allow compatibility with all follow focus systems for smooth, precise focus pulls. The ring comes supplied with a rubber covered band called a GumGum to add protection and reduce the diameter of the inner ring to support the use of smaller diameter lenses measuring 76 82mm.
