Easy Switching between Horizontal and Vertical: Loosen the lock-knob and rotate the camera body to certain stop and then tighten the lock-knob to switch the camera from horizontal to vertical position without removing the camera from ballhead. | Clean Structure: Consists of an inner ring and an outer one. The inner ring is built with a camera plate to be attached on a camera base; and the outer ring is built with Arca-swiss plate at the base (with both 1/4 and 3/8 thread sockets available), can be mounted on different tripod heads. | Easy to Install: firstly attach the camera body on the lens support, then attach the lens on the camera and mount the whole set on the tripod via the Arca-swiss QR plate on the ballhead or mount on a tripod directly via the base thread socket. | Better Stability: by using a lens collar, and install the whole camera and lens kit on a tripod via its base plate making the center of gravity lies between the camera and lens, which provides better balancing and stability. | Works with various camera models: diameter of the inner ring is 80mm, captive slot design on both camera plate as well as inner ring QR mount, which result in better compatibility of the lens support with different camera models, such as Canon 5DIV, 5DIII, Nikon D850, D810, D750, Fujifilm XT4, XT5 and XH2 etc. models combined with bigger lenses. Also, it works well on mirrorless cameras with lens adapters such as Canon R, RP, R5, R6, R7, R8, R6II, Nikon Z, Z6, Z6II, Z7, Z7II and Z8 etc. (Max outer diameter of the adapter should be less than 80mm)
