Zacuto's Lightweight Locking Lens Support includes a Q-mount, Zupport, 1" male rod screwed into the Zupport to give it the height to reach your lens, and a Universal Zip Gear. The Q-mount can ‘snap’ onto rods with the clamps facing up or down and tightens with a quick release ratcheting lever on either side of the mount. It can be installed anywhere on a 15mm lightweight spaced rod system without you needing to remove any other accessories. Your lens rests in the Y shaped support and the ZipGear wraps around the lens for additional security.
