The Acratech Long Lens Head is designed as a telephoto lens support system capable of providing rock solid anchoring for even super telephoto lenses, such as a 600mm f/4 lens. The long lens support system boasts the same freedom of movement, and light weight of the rest of our product line. Although our Long Lens Head is designed primarily for long telephoto lenses with tripod collars, it is also available with an index able clamp* that will allow it to be used with camera lenses that do not have a tripod collar. When the Long Lens Head is used with the camera body attached directly to the head, almost all standard camera positions are accessible (please see our video instruction manual for more information about this). This long lens support system should not be considered as a replacement for a general purpose ballhead, but it does allow the photographer who primarily shoots with telephoto lenses to not be required to carry a second tripod head into the field for occasional shots with standard lenses.
*Our Index able clamp features a knob below the clamp which allows the clamp to rotate and lock into different positions verses the non-index able clamp which actually does index, but will requires an Allen wrench (included) to do so.
