iDC Photo Video SYSTEM ZERO Standard Gearless Follow Focus for Canon 5D MkII

The SYSTEM ZERO Standard Gearless Follow Focus for Canon 5D MkII is an affordable and 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 four dovetail slots on the sliding focusing plate, which in turn mounts to the dedicated base plate beneath the camera.
