iDC Photo Video's SYSTEM ZERO Gearless Wheel Assembly is an additional wheel assembly designed for use with the Canon 70-200mm zoom lens in conjunction with an XL1 Follow-Focus kit. This second wheel adds easier, more precise zoom control to the lens by attaching to one of the seven dovetail slots on the XL1's sliding focusing plate--making it the perfect complement to the already existing focus wheel.
Completely gearless wheel assembly is designed for accurate and smooth zooming.
The slots' dovetail feature captures the wheel assembly for easy fitment.
Zoom wheel accepts white graphic tape for making pre-shot marks.
The zoom wheel port accepts industry standard Arri-style follow-focus whips and cranks.
Wheel assembly will work only with the Canon 70-200mm lens series' zoom ring.
