iDC PhotoVideo Zero XL1 Follow-Focus with Viewfinder for Canon 5D MarkIII

The iDC PhotoVideo System Zero XL1 Follow-Focus with Viewfinder for Canon 5D MarkIII is a versatile follow-focus system designed to lend cinema-like focus control to your DSLR videos. The system's gearless design means that, unlike most other DSLR follow-focus units, this one doesn't require the purchase of dedicated gears to match each lens you use. An adjustable focus wheel attaches to one of seven dovetail slots on the sliding focusing plate, which in turn mounts to the dedicated base plate beneath the camera.

The base plate can use any standard quick-release assembly for mounting onto a rig or tripod. It also accommodates iDC's adapted Hoodman loupe or a Zacuto Z-Finder, if you need to use a larger viewfinder for even more precise focus. When not in use, the focusing wheel can be slid away from the lens and locked in place, or the combined baseplate/focusing plate/wheel can be removed as one piece (using an allen wrench) for easy switching between video and stills shooting.
