The Zacuto 15mm LWS Locking Lens Support is a lens support system for 15mm rods that consists of several of Zacuto's modular components.
The basic building block is the Q-Mount, which clips onto and mounts underneath the 15mm rods. The Z-ZG-16 is a 40.64 cm Zipgear which wraps around either a focus or zoom ring and is used with the special gear locking tightener to provide a perfect fit. This kit also includes the Z-RE-M1 2.54 cm rod extension, which provides extra distance between the Q-Mount and the Zipgear.
