Zoom control for Studio 4K cameras

The Blackmagic Design Zoom Demand is a dedicated accessory that mounts on the pan handle of Studio 4K Plus and Studio 4K Pro cameras via a rosette. It gives camera operators direct tactile control over zoom, record start and stop without touching the camera body. The unit is aimed at live production and studio crews who need repeatable zoom moves from a fixed grip position.

Sustained handling and connection stability

Dual USB connections link the demand to the camera, providing a secure link that resists accidental disconnection during long takes. The rosette mount lets the operator set the handle angle once and keep it locked for the entire shoot. An in/out toggle and a speed selection knob allow continuous zoom speed changes without menu diving, so the feel stays consistent from the first shot to the last.

Replaces menu-driven or on-body zoom

It removes the need to reach for the camera’s built-in controls or navigate touchscreen menus while framing a shot. The upgrade is worth it when the operator works from a tripod or pedestal and needs precise, repeatable zoom pulls with one hand on the pan handle. It does not add zoom capability to cameras that lack motorised zoom lenses.

Questions about this item

How much power does the Zoom Demand draw from the camera when it is running continuously?

The Zoom Demand is powered over its dual USB connections to the camera, so it draws only the small amount of current required for the zoom toggle, speed knob and record button — no separate power supply is needed.

Which camera models and mounting hardware must I already own for the Zoom Demand to work?

You need a Blackmagic Studio 4K Plus or Studio 4K Pro camera and a pan handle with a rosette mount to attach the Zoom Demand.

Will the Zoom Demand operate correctly if I keep using my existing pan handle and rosette setup?

Yes, the Zoom Demand clamps onto any standard rosette on your current pan handle, so it works with the mounting hardware you already use on the Studio 4K Plus or Studio 4K Pro.
