2. Prodott Aktarview and Kit Contents
The LIVE AIR 4 SMART offers a comprehensive upgrade to the motor, featuring a longer scanning range, faster autofocus speed, and more autofocus modes. The controller, related accessories, settings, and operation methods remain consistent with previous models.
2.1. Available Kits
The LIVE AIR 4 SMART is available in several configurations to suit different user needs:
- PD-BTMP-SPM Kit (LiDAR Motor Only): This is the most cost-effective solution for solo shooters. The LiDAR motor handles all autofocus setup and operations independently, requiring no additional controller.
- PDL-AFX-SPM Kit (LiDAR Motor + Compact Wireless Control Wheel): This popular option for solo shooters provides both autofocus and manual control. It includes the LiDAR motor and a compact wireless handwheel for manual focus control. It is also compatible with the Live Air 4 Smart wireless lens control system for zoom functions.
- PDL-AFX-RA-SPM Kit (LiDAR Motor + REMOTE AIR RIG + Full-Size Handwheel): This comprehensive professional solution supports both solo and team shooting. It includes the PDL-AFX-SPM components plus the REMOTE AIR RIG, upgrading the small control wheel to a full-size handwheel for top-tier control and versatility.

Għażla ta' Aġġornament: If you already own a PDL-TC-AFX mini wireless controller or any kit from Live Air 2S or newer, you can purchase the PD-BTMP-SP LiDAR motor as a standalone upgrade. It supports Bluetooth pairing with older Bluetooth motors for seamless integration.
3. Setup
3.1. Mounting the LiDAR Motor
Attach the LiDAR motor to your camera rig using the provided hot shoe clamp or rod adapter. Ensure the LiDAR module has a clear line of sight to your subject and is not obstructed by other camera accessories.

3.2. Lens Gear Ring Installation
Install the lens gear ring onto your camera lens. Ensure it fits snugly and aligns with the motor's drive gear.

3.3. Ixgħel u Tqabbil Inizjali
Insert the charged batteries into the motor and controller (if applicable). Power on both devices. The motor will automatically search for available controllers. Follow the on-screen instructions or refer to the controller's manual for specific pairing procedures.
3.4. Matte Box Compatibility
The autofocus function can still be used with a matte box. Consider these methods:
- Adjust Motor Position: Raise the LiDAR motor as much as possible and find a suitable mounting position to ensure the matte box does not block the LiDAR's scanning path.
- Modalità Kaptan-Skjav: Set the new LiDAR motor to master mode. In this mode, it functions solely as a rangefinder, activating only LiDAR distance measurement and control features while disabling the motor drive. Mount it in a position where it won’t be blocked by the matte box and adjust the angle. Then, connect it to and control a separate Bluetooth motor (e.g., PD-BTMP, PD-BTMP-N, PD-BTMP-S, or PD-BTMP-SP).

4. Istruzzjonijiet Operattivi
4.1. Lens Calibration and Data Saving
Each motor can save data for up to 5 lenses. To calibrate a lens, select a channel color (red, yellow, green, blue, white). Double-click the motor button to cycle through these 5 channels. Use labels to record which lens corresponds to each channel. After restarting the motor, simply set it to the corresponding color channel to extract the calibration data and enable autofocus mode. Changing the device will not affect the saved data.
4.2. Autofocus Modes and LiDAR Scanning Angles
The LIVE AIR 4 SMART features a hybrid LiDAR system:
- 28° Close-Range LiDAR: Defines the autofocus area for subjects up to 4 meters away.
- 4° Long-Range LiDAR: Designed for autofocus in strong outdoor sunlight, with a narrow scanning area.
- 16° User-Adjustable Long-Range LiDAR: An expanded version of the 4° angle, suitable for tracking moving subjects.
You can combine 4°+28° or 16°+28° for autofocus depending on your shooting scenario for higher efficiency and creativity.

4.3. Autofocus Range
The LiDAR module consists of a near-range LiDAR (5 meters, 28 degrees) and a long-range LiDAR (30 meters, 4 degrees; 9 meters, 16 degrees). Effective ranges vary with lighting conditions:
| LiDAR Type | Kundizzjoni | Max Effective Range |
|---|---|---|
| Long-Range (4°) | Indoor + Nighttime | MAX 30M |
| Outdoor, Cloudy Daytime | 15M sa 18M | |
| Outdoor, Daytime (Light Intensity < 10,000 lux) | MAX 18M | |
| Long-Range (16°) | Indoor + Nighttime | MAX 9M |
| Outdoor, Cloudy Daytime | 6M sa 9M | |
| Outdoor, Daytime (Light Intensity < 10,000 lux) | MAX 9M | |
| Short-Range (28°) | Indoor + Nighttime | MAX 4M (typically 3.5M) |
| Outdoor, Cloudy Daytime | 3M sa 3.5M | |
| Outdoor, Daytime (Light Intensity < 10,000 lux) | MAX 3.8M |
Note: Distances may be reduced in higher light intensities (e.g., above 70,000 lux).
4.4. Autofocus Logic and Speed Adjustment
The autofocus feature does not support focus locking. The motor performs calibration and autofocus independently. It operates similarly to area autofocus and narrow (spot) autofocus modes, automatically measuring distance and focusing on the nearest or farthest object detected within the LiDAR's scanning range.
The motor has three speed settings: fast, medium, and slow. You can cycle through these settings by short-pressing the motor button 5 times. Medium speed is recommended for normal autofocus. Use fast for quicker adjustments and slow for smoother transitions.
4.5. Supported Lenses
The autofocus feature supports most conventional cinema lenses with built-in hard stops. It does not currently support non-hard stop DSLR lenses or certain macro lenses with non-linear progressive magnification.
For electronically controlled lenses without hard stop focus but with a depth of field scale, autofocus can still be used. Manual calibration based on the depth of field scale is required. Afterwards, autofocus MARK points can be set.
