Abstract: A device and a method for facilitating the rotation of an adjustment ring from a plurality of adjustment rings of a camera lens. The device comprises a tightening ring having an adjustable diameter and a control lever protruding from the tightening ring allowing a user to rotate the adjustment ring of the camera lens along the lens' longitudinal axis. The method comprises enlarging a tightening ring to an extended diameter larger than the diameter of the adjustment ring and positioning the lever ring device onto the adjustment ring of the camera for frictionally engaging the tightening ring onto the adjustment ring. Applying lateral pressure along the camera lens' longitudinal axis onto a control lever protruding from the tightening ring causes the adjustment ring to rotate.
