Fujinon 4K Broadcast 30x Zoom Lens

Fujinon offers two highly specialized options matching this description, depending on whether you are looking for an affordable, highly agile production lens or an upcoming ultra-premium broadcast lens:

1. The Fujinon LA30x7.8BRM-XB2: A compact, lightweight portable zoom lens designed specifically for 2/3" sensor broadcast cameras (frequently paired with systems like the Blackmagic URSA Broadcast G2). It delivers an incredible 30x ratio in an exceptionally small footprint.

2. The Fujinon UA30x7.3BERD: A higher-tier telephoto broadcast zoom lens designed for premium sports broadcasting, live events, and high-end studio applications.

Key Technology Highlight: The LA30x7.8 Architecture

The LA30x7.8 represents a major engineering shift for shoulder-mounted 4K operators, achieving a long-reach 30x zoom magnification without the historical bulk of traditional telephoto glass.

• Advanced 16-Bit Drive Unit: The lens housing integrates high-resolution 16-bit optical encoders. This ensures that metadata tracking for zoom, focus, and iris positions is completely instantaneous and accurate, making it perfectly compatible with complex virtual studio backgrounds, augmented reality (AR), and remote robotic production sets.

• Rear Focus Mechanism & Low Breathing: By shifting internal elements near the rear of the lens during focus adjustments rather than moving massive front glass elements, the lens minimizes focus breathing (where the image frame sizes shift during focus pulls) and ensures remarkably quiet tracking operation.

• Dynamic Zoom Ramp Speeds: The integrated servo handles extreme performance ranges, driving a lightning-fast snap zoom across the entire 30x range in just 1.0 second (perfect for frantic sports tracking) down to an ultra-smooth, slow crawl taking 120 seconds for cinematic concert transitions.

• Integrated Push-Macro Ring: Operators can instantly slide the main focus ring forward to unlock an onboard macro function, dropping the Minimum Object Distance (M.O.D.) down to just 0.05 meters (1.9 inches) from the front element for extreme detail shots without needing to break away from standard framing grip configurations.

• One-Touch Electronic Flange Back Calibration: Manual back-focus adjustments are eliminated. By pressing a single dedicated button on the drive servo unit, the lens runs an automated routine that instantly calibrates the electronic distance matching between the back lens element and the camera's image sensor plane.
