Lightweight Double-Sided Z-Focus

"Zacuto's lightweight Double-Sided Z-Focus is an extremely accurate follow focus for 15mm and lightweight rods. By using two follow focus drive mechanisms accuracy is increased over typical transmission design. 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 Zacuto Double-Sided Z-Focus (Follow Focus) includes: -Double sided design for operator and assistant use -Completely gear-driven design for slip free, accurate movement -Helicel gear adjustment screw to allow user to tighten up gear play -Interchangeable gear drives -Z-focuses now include a new operator's marking disc that allows the camera operator to see focus marks while operating the camera. -Standard whip port for Zacuto, Chrosziel, or Arri follow focus whips and speed cranks. -Industry-standard 15mm lightweight rod mount -lightweight design -Other gears available in Fuji .6 & Canon .5 pitches The Lightweight Double-Sided Z-focus comes standard with (2) .8 pitch, 1” diameter gears, if another pitch or diameter gear is needed that can be specified when ordering. The diameter of the gear changes the rotation of the lens. The larger the diameter, the further and faster the lens will rotate. If you need more than one gear, those can be ordered separately. "
