The follow-focus can thus be used with the Canon lens to achieve precise focusing and zoom. The Gear Ring is split along a point of its 83.6mm diameter. The split allows the Ring to be opened up to resemble the letter "C" and as a result to easily attach onto the lens. Once on, a screw at the split point securely tightens the Ring onto the lens.
