Blackmagic Design URSA Cine Lens Cable Adapter for B4 Mount

The Blackmagic Design URSA Cine Lens Cable Adapter for B4 Mount bridges the gap between broadcast-style B4 lenses and the URSA Cine camera system, giving you access to a massive range of professional zoom glass without needing to rewire your workflow. This 7- to 12-pin adapter cable handles both power and data transmission, so you get full digital lens control (zoom, focus, iris) while drawing power from an external source rather than the camera body. It’s built for broadcast operators and cinema shooters who want to use their existing B4 broadcast lenses or box lenses on URSA Cine, but it’s also useful for anyone stepping up to cinema cameras who wants flexibility with lens choice. No fuss, just plug it in and you’re running.
