Blackmagicdesign URSA Cine B4 Adapter Cable

Blackmagicdesign URSA Cine B4 Adapter Cable

7-pin to 12-pin lens adapter cable enabling digital control for B4 broadcast lenses

When you integrate cinema cameras into live broadcast workflows, you need direct communication between your camera body and optics. The Blackmagic Design URSA Cine B4 Adapter Cable creates this electronic link. It connects your camera body directly to traditional broadcast lenses while preserving full control functionality during live productions.

Operators maintain high image quality while leveraging rapid servo control on broadcast glass. By bridging the proprietary 7-pin interface on your URSA Cine to the standard 12-pin connector on broadcast optics, this cable forms the reliable electronic backbone of your hybrid rig.

Core capabilities for digital B4 lens integration

Enabling Full Digital Lens Control

Mounting a broadcast lens on a cinema camera usually creates an electronic communication gap due to differing protocols and physical connectors. This cable resolves that gap by passing digital lens control signals directly between camera and optics. Essential zoom, iris, and focus commands pass straight to the lens servos without signal loss.

Live environments demand real-time lens adjustments when lighting or distances shift rapidly. This cable routes communication directly between the camera body and the digital encoders inside your lens. Vision mixers can use standard control surfaces or switchers to adjust parameters remotely with exact precision.

Bridging URSA Cine bodies and B4 broadcast glass

This adapter cable unites two distinct production ecosystems into one streamlined setup. This configuration combines the high dynamic range and large sensors of Blackmagic URSA Cine cameras with the deep zoom ranges and parfocal stability of standard B4 broadcast or box-type lenses.

Connecting these components yields a powerful live production rig. The adapter routes exact power and data signals from the URSA Cine directly to the internal mechanics of your box-type lens. This eliminates third-party control workarounds while keeping your camera pedestal clean and uncluttered.

Live sports and stadium workflow integration

When tracking fast action across a sports field, you need immediate lens responsiveness. Pair your URSA Cine camera with a B4 box-type lens to get maximum focal reach, and use this cable to unlock live lens control from your pan bars. Camera operators can make rapid zoom and iris adjustments with instant servo response while following fast-moving gameplay smoothly.

Secure 7-Pin to 12-Pin Interface Connection

In professional broadcast environments, cable connection reliability keeps your camera chain stable. This cable features a 7-pin connector pinned specifically for the URSA Cine and a standard 12-pin connector for your B4 lens. The exact pinout guarantees correct digital signal routing to each servo inside the lens block.

Built for demanding field use, these locking connectors maintain signal integrity anywhere from a church tripod mount to a studio pedestal. This prevents accidental signal dropouts even during fast panning or aggressive tilting.

URSA Cine system compatibility and hardware requirements

Verify compatibility before configuring your live production setup. This cable serves a specific role: it connects URSA Cine cameras with B4 broadcast- or box-type lenses electronically. It does not adapt optical elements, correct flange distances, or change the physical mount of the lens; it handles the electronic communication between a mechanically mounted B4 lens and the URSA Cine body.

This cable operates strictly as an electronic bridge within Blackmagic workflows, ensuring accurate sync for tally, iris, and zoom data. Note that it requires the camera to be physically equipped with a B4 mount adapter. The cable is incompatible with non-B4 lenses and other camera models.
