Libec Focus Demand for Canon/Fujinon portable lenses

This remote focus demand provides remote servo focus control for both Canon and Fujinon portable broadcast (ENG/EFP) servo lenses. Instead of requiring separate, brand-specific focus demands, the FD-1 is universal; it uses interchangeable conversion cables to match the pin configuration of whichever lens is mounted on your rig.

Core Features & Practical Utility

• Cross-Brand Universal Compatibility: The main unit features a 6-pin output port. By swapping out the connection cable, it translates control commands seamlessly across brands. It can drive either a Canon portable lens via a 20-pin connection or a Fujinon portable lens via a 12-pin connection.

• Tactile Mechanical Wheel with Three Pegs: The control knob features three extended metal pegs for maximum grip. The internal mechanics provide smooth, fluid drag resistance mimicking a traditional large studio box-lens wheel, making fine focus tracking easier to pull off during active live shows.

• Focus Direction Reverse Switch: Operators have varying personal preferences for focus direction. A physical reverse switch on the side lets you change the rotation of the focus wheel instantly without deep menu diving. This layout makes it easy to mount on either the left or right tripod pan handle.

• Aluminum Mounting Clamp: The system includes a rigid, lightweight aluminum alloy clamp that locks tightly around standard video fluid head pan handles without slipping or marring the finish.

Required Connection Cables (Sold Separately)

The FD-1 does not include lens cables in the box. To connect the demand unit to your specific lens servo block, you must pair it with one of Libec's dedicated conversion cables:

• DC-F20 Cable: Connects the FD-1's 6-pin output to a Canon portable lens 20-pin connector.

• DC-F12 Cable: Connects the FD-1's 6-pin output to a Fujinon portable lens 12-pin connector.

Operational System Tips for the FD-1:

💡 The Left-Hand Standard Setup: In traditional multi-camera live broadcast environments, studio operators standardly install the FD-1 Focus Demand on the left tripod pan handle and pair it with a matching zoom rate demand (such as the Libec ZD-1) on the right pan handle. This standardized split layout lets you control focal distance and framing adjustments at the same time without removing your hands from the tripod steering controls.

• Checking Cable Stress Drops: Portable broadcast lenses draw their power directly from the camera body via the lens mount pins or separate power leads to run their internal servo motors. When wrapping the DC-F20 or DC-F12 cable around your fluid head, always leave a small loop of slack near the head's tilt axis. If the cable is too taut, steep vertical tilts can strain the multi-pin connector sockets, causing intermittent focus signal drops or data dropouts mid-shot.
