Press the IRIS dial to switch the method of
adjustment for the aperture of the lens.
The method switches to AUTO IRIS or
MANUAL IRIS with each press of the dial.
AUTO IRIS:
Adjust the iris automatically.
MANUAL IRIS:
Adjust the iris manually.

Turn the IRIS dial to adjust the aperture of
lens when in the manual iris mode.
In the auto iris mode, the lens iris can be
corrected using this dial.
Increase in brightness beyond the maximum
aperture (OPEN) is performed via gain
adjustment (CAMERA mode: 0 to 4 dB).
If further gain adjustment is necessary, assign
HIGH GAIN to one of the USER buttons 1 to
3. The gain mode switches between normal
and high with each press of the button.
Gain can be set to up to 34 dB in high gain mode.
Set the direction of the IRIS DIAL and aperture
control in the setup menus, SW&DISP SETUP
screen, IRIS DIAL.
The lens aperture can be adjusted in the focus
ring by setting the RING switch to IRIS. The
default setting for this item is ZOOM, so set
the RING SW item to IRIS in the setting menu
SW&DISP SETUP screen. The relationship
between the direction of rotation and aperture
control is based on the IRIS DIAL setting in the
SW&DISP SETUP screen. However, as this
will make it impossible to adjust the focus in the
focus ring, please set the focus control method
to AF (auto focus) with the FOCUS switch. Zoom
control can also be assigned to the FOCUS ring.

bottom center of the screen. These displays make
aligning the focus easier and are particularly useful
in manual focus mode. The display that appears

be configured with the FOCUS ASSIST SW item
in the setting menu SW&DISP SETUP screen.
