You can adjust settings such as iris, focus and zoom in the same way you would an
active MFT lens, either via an ATEM switcher using the 'camera control' page, or via
other remote control interfaces that can be connected to the Micro Studio Camera 4K
expansion cable. For a list of supported B4 digital lenses, refer to the
Blackmagic Design support center at www.blackmagicdesign.com/support/faq/59011

S.Bus Digital Servo
By connecting to a compatible S.Bus receiver using the Futaba J cable, you have
17 S.Bus remote channels where features of the camera can be assigned to and
remotely controlled. Channel 18 is reserved as a reset switch so that the camera can be
reset to its default exposure settings. These features can include focus, servo zoom, iris
control and other such features. For more information about mapping functions to S.Bus
remote channels, see the 'Remote Settings' section of this manual.
Wiring diagram for the Blackmagic
Micro Studio Camera 4K Expansion Cable
When using Blackmagic Micro Studio Camera 4K's expansion port you may only want to access
one or two functions. For example, you may want to control an attached B4 Broadcast Lens
while simultaneously receiving 12V power and a reference signal. It's easy to make a connector
that will give you just these functions without the clutter of additional, unused connectors.
Use the following diagram when wiring the expansion cable included or use it as an example for
how you can wire up the connections on your own custom cable correctly. The full range of
available pins are listed under group P1, while the subsets used for particular functions, as well as
their layout within the appropriate connectors, are shown in groups P2 through P7.
