Support heavier lenses with your 15mm LWS rig by attaching the Wooden Camera Universal Lens Support. When connected to a cinema lens's support foot or a still photo lens's tripod collar, the lens support removes the weight stress from the camera's lens mount. Included with this support are 3 screw-on caps: one with a 1/4"-20 screw, a short 3/8"-16 screw, and a taller 3/8"-16 screw. For lenses that don't have a support foot or tripod collar, the included rolling y-bracket can be placed anywhere along the barrel of nearly any lens regardless of diameter. The rubber rollers allow the bracket to be placed on a rotating part of the lens, i.e. the focusing ring.
