Interface / Connectors / Encoders:
• It has 3 connectors each with 20 pins, allowing precise positional readouts (zoom, focus, etc.), especially useful in virtual / augmented systems.
• A high‑resolution 16‑bit encoder is used to detect the precise position for calibration and tracking (without needing lens re‑initialization) in systems combining real and virtual images. -
Optical design / coatings: It uses advanced lens coatings and design to suppress chromatic aberration, flare, and ghosting across the full field to support UHDxs / 4K image quality.
-
It retains a compact and relatively light form for a broadcast lens in its class.
