Although the Acratech Long Lens Head is designed primarily for long telephoto lenses, it is available with an indexable clamp that will allow the long lens head to be used with cameras that do not have a lens with a tripod collar.
When the Long Lens Head is used with the camera body attached directly to the head nearly all camera positions are accessible.
The Long lens head should not be considered as a replacement for a ballhead for general photography but it does allow the photographer who is primarily shooting long lenses to not be required to carry a second tripod head into the field for occasional shorter lens shots.
