The Spider Camera Holster SpiderPro Lens Collar Plate V2 is designed to attach to the bottom of a foot on a telephoto lens collar, and it is recommended to use with telephoto lenses that range in size from 70-200mm and larger. Furthermore, the plate has threaded sockets on either side, so the pin can be switched for left- or right-handed users. Additionally, the aluminum and stainless steel plate has a dovetail on the bottom, which is compatible with Arca-type ball heads or clamps.
Anti-slip rubber grips and anti-rotation features help keep the plate aligned with the lens
