The Z-Drive slides onto a single 15mm diameter rod (on the left or right of your camera) and tightens in place next to your lens with a Zacuto quick-release ratcheting red lever. It comes with a fixed 1 ¾” diameter .8 pitch gear to connect to your lens. If your lenses are not pitched to .8 or are not pitched at all (most DSLR and basic video camera lenses are not) you can add our Zipgear Universal to your lens so the teeth match our gear correctly for smooth rotation. The ZipGears can be cut to fit the circumference of your lens and tightened with an Allen key. These ZipGear straps are pitched to .8 and are 13.5” long. With some smaller lenses a larger gear for the Z-Drive may be helpful. The 60mm Z-Drive Gear screws directly to the gear of Z-Drives purchased after Dec 8,2015. If you have an older version of the Z-Drive and want to upgrade to the newer Z-Drive to allow for the larger gear, email firstname.lastname@example.org. There is a $75 charge for the upgrade.
The Z-Drive has a slender marking disc to create distance marks for repeatable focus pulls and a standard whip port. We recommend using the Z-Drive with our Tornado grip when working handheld. The Tornado attaches to the Z-Drive whip port and works in tandem with the Z-Drive to create a unique mechanical follow focus handgrip perfect for single operator shoulder mounted work.
PLEASE NOTE: The Z-Drive is not compatible with matte boxes when working shoulder mounted. The Z-Drive's max operating temperature is 100 degrees F.
