Blackmagic Design BMD-CINSTUDMFT/H/FD Focus Demand Control / Dual USB-C / ARRI Hirth Rosette / Pan Handle Mount

Description

The Focus Demand is a compact hand-operated focus control that attaches to a pan handle to provide precise mechanical focus adjustments. It is designed to add handle-mounted focus operation to compatible studio cameras and integrates a tactile control layout for quick, repeatable moves. The unit is engineered for studio environments where operator ergonomics and responsive control are essential.

Key features include a rotating focus knob with three equally spaced levers to improve grip and speed of adjustment. The device uses dual USB-C connections for power and control connectivity and secures to an ARRI/Hirth rosette for robust mounting. The mechanical design emphasizes low play and a consistent feel across the entire rotation range.

Technically, the Focus Demand provides direct focus control using a precise rotary encoder mechanism coupled to the camera control interface. The dual USB-C connectors supply both communication and redundant connectivity options to maintain reliable operation. The physical control includes three levers mounted around the knob to enable rapid fingertip adjustments under live conditions.

Connectivity is handled via two USB-C inputs that connect to compatible camera models and control processors. The ARRI/Hirth rosette attachment ensures secure integration with professional pan handles and support rigs. The unit is compatible with Studio 4K Plus and Studio 4K Pro cameras when paired with the appropriate camera control interface.

Typical applications include studio camera operation, live production switching workflows, and any multi-camera broadcast setup where handle-mounted focus control speeds operator response. It is suited for ENG and studio crews who need mechanical, tactile control that integrates cleanly into existing pan head assemblies. The lightweight form factor reduces added mass on the pan handle while preserving full operator dexterity.

Installation is straightforward – the Focus Demand mounts to a standard ARRI/Hirth rosette on a pan handle and connects via USB-C to the camera or control module. The ergonomic layout and robust build are intended for repeated daily use in production environments. The device is designed to meet the durability needs of broadcast workflows while remaining simple to set up and operate.
