The Cullmann Magnesit 550 Monopod is an intelligently-designed mobile support for use with large SLR cameras and the large, bright telephoto lenses professionals often use, such as a flagship-class SLR with a 300mm f/2.8 lens. Even when using smaller items, the large maximum tube diameter can benefit your image sharpness in tough conditions. It extends to ~5', collapses to ~18", and has a 28mm maximum diameter upper tube.
The 550's named the 'Magnesit' because of its extensive use of magnesium in the casings and fittings. Magnesium's a light and stable metal, helping to contribute to the quite tolerable weight of just 1.4 pounds, an excellent number for this size of aluminum-based monopod.
