This picture shows the (optional) Panosaurus Landscape Tower for fish eye lenses.  This  6" tall attachment is designed specifically for users wishing to shoot with fisheye lenses - with as little of the tripod and head appearing in the images as possible. The tower itself and the camera mounting pad can both move freely forward and backward and each are secured with clamping knobs from underneath.  This enables the sometimes-difficult-to-work-with fisheye lenses to rotate around their optical center with most of the head itself "out of the way".
