The Giottos MM 9150 Monopod is a 4-section professional class model made from aluminum, with 32/28/24/20mm diameter segments. You can use the MM 9150 with the very largest of lenses, such as a 400mm f/2.8 or 600mm f/4, though it is ideal for use with slightly smaller rigs such as a 300mm f/2.8 or 500mm f/4.
The MM 9150's rubber foot is broad and slightly springy, and that helps it to get a firm grip on many surfaces. The MM 9150 also has a comfortable hand strap and some foam padding wrapped to the top.
