Zacuto .8 Pitch 2 1/4 Diameter Gear has been discontinued, here are some related products you might like:
The Zacuto 0.8 Pitch 2-1/4" Diameter Gear is used with the Z-Focus follow focus unit. Substantially larger than the standard 1" gear, this adds speed and range to the rotation of your lens.
If you are using a Z-Focus that was purchased before January of 2010, please call for a different style gear. This gear will not work with your Z-Focus.
Note: The diameter of the gear changes the rotation of the lens. The larger the diameter, the further and faster the lens will rotate.
