The RED LENS SUPPORT 15MM (LIGHTWEIGHT) slides onto your lightweight 15mm rail system to support longer, heavier lenses. This product uses a 1/4"-20 tie-down thumbscrew and a 3/8"-16 reducer in order to accommodate all available lens configurations, without the need for tools. The center locking support allows horizontal travel of 2.5mm and vertical travel of 3.5mm for quick adjustments when mounting to your lens. Even with a matte box and follow focus attached, you will be able to attach and remove your lens support without interfering with your configuration.
NOTE: The product video features the RED LENS SUPPORT 19MM. Product does not include black lens support columns or yoke (as shown in configured image).
