Haoge 350mm Y-Type Telephoto Lens Support Bracket Long-Focus Holder with Double Clamp and Quick Release Splint Plate Compatible with Arca Swiss Kirk RRS Sunwayfoto Hejnar Benro Sirui The Haoge Y-type Telephoto Lens Support is an Arca-compatible combination specifically designed to provide a stable platform for your camera body and telephoto lens. The bracket utilizes a sliding Arca-type double Clamp and a Plate which adjust along the main bar to accommodate different lenses and offer a quick release system. A height adjustable forward support uses two rotating discs which allow the lens to be held steadily without hindering the use of the focus, zoom, or rotation collars. The operation of the camera with the big lens on a tripod head is much safer and easier. Note: The item can not fit level-release system of RRS / Markins / Vanguard and other brands.
