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 left 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.
Auto Focus Button
The auto focus button is located at the bottom left corner of each camera controller. Press to
automatically set the focus when you have an active lens that supports electronic focus
adjustments. It’s important to know that while most lenses support electronic focus, some
lenses can be set to manual or auto focus modes, and so you need to ensure your lens is set to
auto focus mode. Sometimes this is set by sliding the focus ring on the lens forward or
backward. On B4 lenses with servo zoom control, you will need to set the switch at the bottom
of the handgrip to ‘servo’.
Click on the auto focus button or drag the manual focus
adjustment left or right to focus a compatible lens
Manual Focus Adjustment
When you want to manually focus your lens using ATEM Camera Control, you can use the focus
adjustment located at the bottom of each camera controller. Drag the wheel control left or right
to manually adjust focus while viewing the video feed from the camera to ensure your image is
nice and sharp.
Manual focus control is only available from your switcher when using B4 and PL lenses with
servo focus controls. As EF lenses do not have servo focus this option is not available when
using EF lenses.
NOTE
Analogue B4 lenses do not support ATEM zoom control. For more information
on analogue B4 lenses refer to the 'using servo zoom lenses' section
