50 m Seamless Focus. Limitless Cinematic Potential.

At its core, LIVE AIR 4 SMART is not just a focus tool — it’s a leap ahead in autofocus innovation. With its hybrid LiDAR + AI virtual focus system, it fuses compact elegance with breakthrough precision. Whether you’re capturing sweeping wide shots or razor-sharp closeups, every frame becomes more intentional — and every take more impactful.

Hybrid Zoom LiDAR System

By combining three LiDAR scanning modes — point, line, and plane — LIVE AIR 4 SMART adapts to every shooting scenario.

  • 4° Point Scan — directional, long-range precision (up to ~50 m under favorable conditions)

  • 16° Line Scan — balanced coverage for mid-range scenes

  • 28° Plane Scan — broad-area scanning ideal for close-range, dynamic framing

The system can operate in hybrid scanning modes (e.g. plane + line, plane + point) for seamless transitions and consistent focus.

AI-Driven Virtual Lens Modeling

The system integrates advanced algorithms trained on over 500 lens models. It intelligently selects and fine-tunes virtual data to predict focus trajectories, ensuring stable performance even when subjects move beyond LiDAR range.
With real-time trajectory prediction, it continues focusing smoothly — even through occlusions or rapid motion.

Dual LiDAR Coordination

A wide-angle short-range LiDAR (28°) works in tandem with a variable narrow-angle LiDAR (4°/16°).
The system automatically adjusts scanning behavior based on focal length and subject distance, maintaining uninterrupted focus transitions.

Double Power Mode & High Refresh Rate

When powered via USB-C with sufficient voltage, the system activates Double Power Mode, boosting performance to:

  • 960 Hz LiDAR refresh rate

  • 1.2 Nm peak motor torque
    This delivers frame-accurate focus response, even during high-speed motion.

Advanced Focus Control

  • Three speed presets: Fast, Medium, Slow — adapt focus response to your style

  • Foreground/Background focus switching within the scan field

  • Master/Slave mode allows the LiDAR motor to control or synchronize with another

  • Full manual wireless control available for precision pulls

From handheld shots to car rigs, Live Air 4 Smart locks on and never lets go.

Perfect for:

  • Gimbals and handheld setups

  • Vehicle-mounted and robotic systems

  • High-speed sports or action sequences

  • Virtual production environments

  • Solo filmmakers needing compact precision
