Blackmagic URSA Cine B4 Adapter Cable

URSA Cine B4 Adapter Cable is a lens control cable for Blackmagic URSA Cine cameras fitted with B4 broadcast lenses. It converts the 7-pin EXT control connector on the front of the URSA Cine to the 12-pin Hirose lens control connection used on professional broadcast B4 lenses, passing zoom, focus, and iris control between camera and lens.

It is the control link that completes a B4 broadcast lens setup on URSA Cine, working alongside the URSA Cine Mount B4. Blackmagic part number BMD-CINEURSABMNTACB4.
