Includes five adapter rings and a storage drawstring bag. The adapter ring screws onto the front of the lens firmly and features filter threads to add circular filters such as variable ND filters and CPL filters on the front of the adapter ring. In addition, the adapter rings are designed with an anti-twist edge to prevent accidental disconnection when used in conjunction with the matte box to ensure safety.
