URSA Broadcast control and playback buttons
Iris
The 'iris' button activates the automatic aperture setting on compatible lenses. When
using video dynamic range settings, a single press of the iris button will set an average
exposure based on the highlights or shadows in your shot. When using film dynamic
range settings, pressing the iris button sets your exposure to the brightest highlight in
your shot. This button works with compatible EF lenses and PL lenses connected with
a compatible broadcast lens controller.
To set your aperture manually, press the forward and reverse skip transport buttons.
Focus
When using a B4 or EF that supports electronic focus adjustments, press the ‘focus’
button to activate auto focus. A white focus square will appear on any viewfinder
or monitor connected to your URSA Broadcast. Anything within the square will be
correctly focused. When the lens is focused, the square will disappear.
Program
The program button is marked PGM and lets you switch the LCD between the camera
view and any signal plugged into the 12G-SDI input on the rear panel. This means if
you’re using the camera in a live broadcast, you can plug in the switcher’s program
output and monitor it during the shoot. Press and hold the program button to see your
program feed. The program feed will continue to display whilst the program button is
being held.
If you want to lock the monitor to display the program input feed, then double press the
program button to lock the display to the program feed. Pressing the program button
again will exit the program feed and return to the camera view.
Playback Control Buttons
The playback buttons let you start and stop playback, plus skip to the next or previous
clip. When using an EF lens, the forward and reverse skip buttons can also be used to
open or close the iris when using compatible lenses. Refer to the ‘playback’ section for
more information on how to use the playback buttons.

NOTE
To use the 'focus' button, your B4 lens must have servo focus control,
with the servo activated. See the 'getting started' section for more information.
Some EF lenses have both manual and auto focus modes. If using the optional
EF lens mount, in order for URSA Broadcast to be able to auto focus with your
lens, you need to ensure that your lens is set to auto focus mode.
