Vocas 1:1.75 Ratio Gear Unit for MFC-2 Follow Focus

SKU CH-JS1Z-25JFY

A 1:1.75 ratio gear unit that adds precise, smooth focus control for long-throw cine lenses on the MFC-2 follow focus system

  • Precise focus control on CINE lenses via 1.75 ratio
  • Smooth adjustments with robust gear construction
  • Integrates directly with MFC-2 follow focus system
  • Compact 7.62 x 5.59 x 3.56 cm form factor
  • Lightweight 144.58 g design minimises rig weight

What It Is

The Vocas 1:1.75 Ratio Gear Unit is a precision accessory built for the MFC-2 follow focus system. It provides a 1.75 transmission ratio that suits CINE style lenses with long focal ranges. The unit weighs 5.1oz and measures 3.0 x 2.2 x 1.4 inches. It is designed for camera operators who need smooth, repeatable focus pulls on cinema glass.

How It Fits

The gear unit mounts directly onto the MFC-2 follow focus, replacing or supplementing the standard drive gear. Its 1:1.75 ratio reduces the hand-wheel rotation needed for a full lens throw, freeing the operator to keep both hands steady on the rig. No additional motors, cables or power sources are required; it works purely through the mechanical interface of the MFC-2.

Who It Suits

This unit suits focus pullers and owner-operators using CINE lenses that demand a higher gear ratio for precise control. It is not for users of still-photography lenses with short focus throws, nor for shooters who rely on wireless motor systems instead of a mechanical follow focus. Builders without an MFC-2 system cannot use this gear unit.
