Cam driven focus system and chassis style lens housing allow matte boxes and other accessories to be attached to the front of the lens, without affecting focus movements. The benefit of zero backlash and image shift give accurate dual focus scales that repeat on direction and change with the cam drive system, giving a wide spread of markings through the scale.

For attachment to focus, zoom or iris barrels of the lens. Wholly manufactured at True Lens from black acetal (Delrin) these gears are individually bored to lens location diameter.

Gears are bored 0.2/0.3mm interference diameter size (diameter and material dependant), heated and allowed to cool in position to grasp with an even pressure to the location diameter. 

Can be secured to metal, plastic or flexible (rubber) surfaces.

Double stepped or shouldered diameters can be machined which will enable gears to run concentric and true to lens.

Suitable for non extending barrels when using fixed position follow focus units.

Standard 0.8MOD pitch gear teeth to match cine style follow focus gears.

Allow a minimum of 4.00mm solid acetal beneath root of gear when determining bore size.

Free measuring and fitting service available, return packing and carriage charges applicable.
