Sigma Tripod clamp TS-81

This tripod clamp from Sigma is compatible with the Arca Swiss system and its mount and is specially designed for the "150-600mm F5-6.3 DG OS HSM Sports". However, you can also use it with the "500mm F4 DG OS HSM Sports". The bar was deliberately designed to be long so that you can precisely determine the center of gravity. This way, you also have an optimal balance when using accessories such as a battery grip or a tele-converter just as you do when Zooming.

Once the tripod clamp is attached to the lens, you can attach the lens hood to the lens in the opposite direction and store the lens in the original quiver with the tripod clamp attached. The safety screws protect the lens from falling down.
