Libec Zoom control for ENG lenses

For operators managing Electronic News Gathering (ENG) and Electronic Field Production (EFP) broadcast lenses, Libec offers industry-standard zoom solutions. ENG lenses from Canon and Fujinon rely on multi-pin analog and digital interfaces to drive internal lens servos, and Libec provides controllers designed to handle these systems.

1. The Compact Option: Libec ZC-9Pro

The ZC-9Pro is Libec's most popular, high-efficiency compact thumb controller for ENG lenses. It connects directly via an industry-standard 8-pin connector, which is the native interface for standard Canon and Fujinon broadcast lenses.

• Dual-Lens Toggle: Features a physical switch that alternates internal communication logic between Canon and Fujinon protocols, eliminating the need for external signal boxes.

• Variable Speed Rocker: Uses an ergonomic thumb rocker. Subtle pressure yields slow, creeping zooms, while pushing further accelerates the internal servo to its maximum tracking speed.

• REC/RET Functionality: Includes a dedicated record trigger button that can be switched to act as a video Return (RET) preview monitor switch.

• Universal Clamping Core: Mounts securely to circular tripod pan handles, jib arms, and crane handles ranging from 0.39" to 1.18" (10mm to 30mm) in diameter.

2. Premium Studio Option: Libec ZD-1

For full studio pedestal layouts or complex OB (Outside Broadcast) operations, the Libec ZD-1 Zoom Demand provides a robust, full-hand grip layout.

• Direct Multi-Pin Support: Built to match modern portable broadcast lenses, natively managing digital and analog signal flows.

• Maximum Speed Limiter: Includes a physical rotary dial on the handle chassis. This allows you to cap the top speed of the servo drive, ensuring uniform, repeatable zoom speeds regardless of sudden movements on the pressure toggle.

• Reversible Zoom Direction: Features an invert switch to flip the Telephoto/Wide configuration based on user preference or mounting style.

3. Multi-Pin Adapter Cables (For 12-Pin & 20-Pin ENG Lenses)

While the standard controllers terminate in an 8-pin interface, modern broadcast configurations frequently use 12-pin (Fujinon) or 20-pin (Canon digital) communication blocks. Libec provides short factory adapter cables to bridge these systems:

• Libec A-12P (8-Pin to 12-Pin Adapter): Adapts the controller to interface with Fujinon 12-pin portable servo broadcast lenses.

• Libec A-20P (8-Pin to 20-Pin Adapter): Bridges the controller over to Canon 20-pin digital servo zoom lens blocks.

• Libec EX-530Pro (Extension Cable): Provides an additional 3.0 meters (9.8 feet) of cable length to route the demand wire smoothly along crane setups, large jib arms, or studio pedestals without creating line tension.
