This monopod is designed for the SERIOUS and heavy-duty photographer. THE PRO POD is perfect of long telephoto lenses like the 400mm f/2.8, 500mm f/4.5 or even a 600mm f/4. It holds 20 lbs. of camera, lens and equipment.  Simple and rugged, The SLIK PRO POD uses aluminum tubing and heavy-duty twist lock with large rubber grips for more comfort. Attach a long lens directly to the monopod using the standard 1/4-20 threaded post or a variety of ball heads.
