ARRI Two-Speed Knob, left

Precision Focus Control

The ARRI Two-Speed Knob (Left) is a specialized follow focus accessory designed for high-precision lens control. Featuring an integrated planetary reduction transmission, this knob allows for significantly finer adjustments than standard focus wheels.

Optimized for Compressed Scales

This unit is particularly useful when pairing the FF-4 follow focus with ENG/EFP lenses or other optics that feature compressed focus scaling. By slowing down the rotation ratio, it provides the operator with greater tactile feedback and accuracy during critical focus pulls.

• Compatible with ARRI FF-4 follow focus systems
• Left-side mounting configuration
• Ideal for lenses with short focus throws
