The Opteka 15mm Lens Support Bracket for DSLR Rigs is used to support heavy lenses on camera rigs, removing the bulk of the weight and pressure from the camera lens mount. It fits onto such DSLR rigs as the Opteka CXS-500 DSLR cage, with cinema standard 15mm rods. It slides along the rails to adjust and adapt to each individual lens for maximum compatibility. Engineered from high quality, machined aircraft-grade aluminum, it features an adjustable height bracket which can be used with a wide variety of lenses. The rail attachment and height bracket system features thumb screws for tightening.
