Blackmagic Design Zoom Demand

This Zoom Demand helps get zoom control of MFT lenses with power zoom when using Blackmagic Studio Cameras. Now you can control lens zoom from the tripod handles and hardware is included for mounting the zoom demand onto tripod handles. This unit even includes buttons for triggering camera functions. The zoom demand can be added to turn affordable photography lenses into amazing broadcast lenses. This unit has two USB‑C ports, so you can daisy chain it to the focus demand unit then connect to the camera with a single USB connection. The design has an incredibly precise feel and so you get very fine lens control, and you can frame and adjust the lens without taking your hands off the tripod handles. The buttons can be customized so you can assign different camera functions to them! Plus, hardware is included for mounting the zoom demand onto tripod handles.

Zoom F1

The zoom function button 1 by default is mapped as a record button for recording to an external drive connected to an available USB-C port on your Blackmagic Studio Camera.

Zoom F2

The zoom function button 2, on the other side of the controller, is an identical button that performs the same function. It allows for left and right-handed control. By default, it is set as a quick zoom function that instantaneously punches into the live image.

Zoom F3

On Blackmagic Studio Camera 4K Pro, this zoom function button 3 is set to program return by default. This would normally be a switcher’s program return feed, but can be any SDI signal connected to your camera’s SDI input. On Blackmagic Studio Camera 4K Plus, the default action is set to auto white balance.

Zoom F4

On Blackmagic Studio Camera 4K Pro, the zoom function button 4 is set to push to talk by default. When connected to an ATEM switcher via SDI, press and hold the button to communicate with the switcher operator. On Blackmagic Studio Camera 4K Plus, the default action for this button is set to frame guides.

Daisy Chain

The Blackmagic Design Zoom Demand unit has two USB-C ports. Each unit is supplied with a 1-meter long USB-C cable which is connected directly from either of your studio camera’s USB-C expansion ports to the demand unit’s input port. If you are using both focus and zoom demand units, daisy-chain them together by connecting the first unit to the second unit via a USB-C interface.
