0.8 Mod 43-Tooth Focus Gear

This 0.8 mod focus gear is a precision accessory built for the FF-T05 Follow Focus system. It provides a direct mechanical link between the follow focus unit and a lens with a 12mm pitch. The 43-tooth design is intended for camera operators who require accurate, repeatable focus control during professional video production.

Durable Construction for Professional Rigs

The gear is manufactured from robust materials rated to withstand the daily demands of professional cinematography environments. Its construction ensures a secure mesh with the follow focus drive gear, minimising slippage or backlash during critical focus pulls. This reliability allows operators to maintain consistent performance across long shooting schedules without gear degradation.

Upgrade for FF-T05 System Compatibility

This component replaces worn or missing drive gears on the FF-T05 Follow Focus, restoring the system's original precision. The upgrade is worth it when an existing gear shows tooth wear that introduces play into the focus mechanism. It is not suited for follow focus units that do not accept the 0.8 mod standard or lenses with a different gear pitch.

Questions about this item

What is the 0.8 mod pitch and how does it affect gear meshing?

The 0.8 mod pitch matches the standard follow focus tooth profile so the 43-tooth gear meshes cleanly with the FF-T05 drive gear without binding or backlash.

What lens diameter does the 12 mm inner bore fit?

The 12 mm bore slides onto lens barrels that measure 12 mm at the focus ring, which is common on many cinema primes and some photo lenses.

How do you secure the gear onto the lens focus ring?

Position the gear so its teeth face the follow focus unit, then tighten the set screw against the lens barrel — the step often missed is checking that the gear rotates freely through the full focus throw before locking it down.
