I’ve now made several purchases from Leofoto and every piece has worked flawlessly. My latest purchase is the Replacement Foot for my Nikon 600 f/4 TC VR S. I works perfectly on both my LeoFoto Gimbal, Wimberley and the other Arca-Swiss heads in my collection. It took no time to securely attach it to the lens and since it is long enough, finding the balance point on my gimbals is very easy. Using it as a carry handle makes the lens and Z9 body comfortable in my hand. Well designed, well built and works perfectly.
