Canon CR-30 Clamper for Studio/Field Lens Controls (Black)

The black CR-30 Clamper from Canon is a large clamping device that allows users to mount a Canon Studio/Field lens controller, such as a servo zoom control, an AF servo focus control grip, or a DIGI focus control, onto a standard tripod handle. It is designed to work with the heavier controllers typically used with Studio/Field lenses that are used to shoot professional sports played in large stadiums, such as NFL and MLB.
