Blackmagic Design URSA Cine Lens Cable Adapter for B4 Mount

Overview

The Blackmagic Design URSA Cine Lens Cable Adapter for B4 Mount is a dedicated adapter cable designed to connect B4 broadcast and box-style lenses to compatible Blackmagic URSA Cine cameras. By linking the camera’s 7-pin EXT connection to a 12-pin Hirose lens interface, it allows supported B4 lenses to be integrated into URSA Cine workflows while enabling digital lens control and external lens powering.

This adapter is intended for professional broadcast and cinema environments where traditional B4 lenses need to be used with URSA Cine systems. It provides a practical bridge between the camera and lens, helping operators maintain lens control functionality while supplying power from an external source for compatible broadcast-style optics.

Core Features
