The Bright Tangerine 15mm LWS Lens Support with 3/8"-16 Post rigidly supports your lens on 15mm rods. It includes a removable 3/8"-16 post that attaches to the center of the support and supports the lens to reduce its load, and it can be vertically adjusted by up to 18mm to accommodate a wide range of lenses. The support features two 3/8″ anti-twist accessory ports and a quick-release lever for ease of use.
