Zacuto's Studio Z-Focus is an extremely accurate follow focus for 15mm and 19mm studio rods. The mechanism utilizes a set of gears that connect to and spin the focus ring or Zacuto zip gear on the camera lens. The white disk allows the focus puller to create distance marks for repeatable focus pulls. The Studio Z-focus has a new flippable design so you can quickly remove the follow focus and flip it from the operator to the assistant side in seconds.
The Studio Z-focus comes standard with a .8 pitch. If you need more than one pitch, those can be ordered separately.
