Iris/Pedestal Control
The iris/pedestal control is located within the cross hairs of each camera controller. The control
illuminates red when its camera is on air.
To open or close the iris, drag the control up or down. Holding the shift key allows only iris
adjustments.
To darken or lift the pedestal, drag the control left or right. Holding the command key on a Mac,
or the Control key on Windows, allows only pedestal adjustments.
The iris/pedestal control illuminates red
when its respective camera is on air.
Zoom Control
When using compatible lenses with an electronic zoom feature, you can zoom your lens in and
out using the zoom control. The controller works just like the zoom rocker on a lens, with
telephoto on one end, and wide angle on the other. Click on the zoom control, located above
the coarse slider, and drag up to zoom in, or drag down to zoom out.
If your lens does not have active lens control or your camera does not support zoom control via
the SDI camera control protocol then these settings will have no effect. If you are using
Blackmagic Studio Camera or Blackmagic Studio Camera 4K, please make sure you have
updated your camera software to v1.9.11 or later to ensure your camera has support for
controlling MFT lenses with active zoom.
Coarse Setting
The coarse setting is located to the left of the iris/pedestal control and is used to limit the iris
range. This feature helps you prevent over exposed images from going to air.
To set your coarse threshold, completely open the iris using the iris control, then drag the
coarse setting up or down to set optimum exposure. Now when you adjust the iris, the coarse
threshold will prevent it from going above optimum exposure.
Iris Indicator
The iris indicator is located to the right of the iris/pedestal control and displays a visual
reference so you can easily see how open or closed the lens aperture is. The iris
indicator is affected by the coarse setting.
