The 18-80 Lens Support is a foldable lightweight support that works with any height adjustable 15mm rod. The 18-80 Lens Support screws into the 18-80 Lens in place of the Canon ¼ 20 support foot. Using the turn of the EF lens, the support firmly clips into place on the 15mm rod. When not in use it folds against the lens for easy storage.
