This universal 15mm rod lens support system is designed to cover your bases no matter the lens size or type. This camera support system includes extensions that make it easy to adapt to various lens mounting styles or even to support matte boxes. The extensions have holes that allow users to tighten parts securely to the Base Extension Rod. The Wheeled Lens Support is intended for lenses that do not have room for the V-Lens Support. They can then rest on areas of the lens that still require rotation. The single-sided rail block enables users to mount or remove support without having to detach other accessories from their rig.
