Focus Demand Zoom Control

The Blackmagic Design Focus Demand is a dedicated zoom controller built for Studio 4K Plus and Studio 4K Pro cameras. It mounts on tripod handles to give operators direct, tactile command of the lens without reaching for the camera body. This accessory targets studio crews and live-production teams who need broadcast-style lens control during extended shoots.

Dual USB sustained operation

Two USB connections provide a stable link to compatible cameras during long recording sessions. The wired design avoids wireless drop-outs and latency that can appear in crowded RF environments. Continuous power over USB means the unit runs as long as the camera is powered, with no internal battery to manage or recharge mid-production.

Replaces manual lens adjustment

This control removes the need to turn the lens barrel by hand, which introduces vibration and limits precision on tripod-mounted setups. The upgrade is worthwhile when operators must hold focus or execute smooth zooms from the pan-bar position for hours at a time. It does not add focus-pull functionality for cameras outside the Studio 4K Plus and Pro range.

Questions about this item

How much power does the Focus Demand draw from the Studio Camera over its dual USB connections during all-day shoots?

The unit is powered entirely through its two USB links to a compatible Studio 4K Plus or Studio 4K Pro camera, so no external supply is needed.

Which specific camera models must I already own for the Focus Demand to function?

It works only with Blackmagic Studio 4K Plus and Studio 4K Pro cameras that provide the required dual USB ports.

Will the Focus Demand still operate if I keep my older Blackmagic Studio Camera 4K (non-Plus/Pro) on the same tripod?

No — the older Studio Camera 4K lacks the dual USB interface, so the Focus Demand cannot connect or draw power from it.
