Designed for the Canon XL 16x line of manual lenses, the FC-X lets you make precise focus adjustments from the tripod handle, helping you keep the shot steady at all times. The FC-X is distinguished by a hefty rotating grip, which drives the focus gearbox using a wound-core, 40-inch cable. The end result is a handy camera accessory that accommodates any tripod configuration while providing smooth manual control. In addition, the handle and cable are fully compatible with other VariZoom gear boxes, so you aren't restricted to a single control only. Made of aluminum, stainless steel, and brass, the FC-X also includes an articulated swivel clamp for angular position adjustments.
