TS-81 Tripod Collar

The newly developed TS-81 tripod socket is designed for ease of use when photographing with the Sigma 150-600mm 5-6.3 DG HSM OS Sports lens. With the ability to adjust the center of gravity, the new optional tripod socket also features safety screws to prevent the lens from falling and improved balance when the lens is extended as well as when using a teleconverter or battery pack. Two mounting threads are used, 1/4 and 3/8, for use with an Arca Swiss quick release plate or other tripods.
