Precision Control for Small Cinema Primes

The ARRI 0.8 Mod 35-Tooth Drive Gear (K2.65276.0) is a high-precision follow focus component designed to drive smaller prime lenses and vintage 16mm zoom optics. Engineered with standard 0.8 pitch module teeth, it provides exact, slip-free engagement with standard gear rings. Its smaller 35-tooth diameter keeps the focus drive mechanism close to the camera body, preserving clearance on tight camera rigs.

Wide 10mm Engagement Surface

Designed to handle subtle physical variations in vintage or specialized lenses, this drive gear features an expanded 10mm face width. This extra surface area ensures that even if a lens barrel moves slightly forward or backward during rotation, the drive teeth remain fully engaged, preventing skipping or binding during critical focus movements.

Seamless Modular Integration

Built to strict ARRI factory dimensions, the K2.65276.0 mounts quickly to the drive arm of standard ARRI manual follow focus units, including the MFF-1, MFF-2, FF-4, and FF-5 systems. The quick-release mounting mechanism allows camera assistants to swap drive gears in seconds to adapt to changing lens configurations on set.
