Adjusting the Aperture
The camera offers the following two ways to adjust the aperture but available aperture values will vary
depending on the lens attached.
Manual aperture: Adjust the aperture value manually using the joystick. Available when the camera mode is
set to [Av], [AGC] or [Manual].
Push Auto Iris: Momentary automatic aperture. Press a button to temporarily adjust the aperture automatically.
Available only when the camera mode is set to [Manual].
The camera also allows you to compensate for the exposure obtained during automatic exposure as well as
select the light metering mode.
Required settings on EF Cinema lenses
To adjust the aperture from the camera, you will need to enable automatic adjustment using the controls on
the lens. Required settings vary depending on the lens. Refer to the following table and the instruction manual
of the lens used.

When using a compatible EF Cinema lens
(
A
Setup Guide )
- As you close down the aperture, the aperture value will be displayed in gray (when the iris is almost fully
closed) and then will change to [Clsd] (in white). Still, the iris may not be fully closed even when the
onscreen display appears as [Clsd].
- When you change the aperture value from a position of fully open or fully closed iris, multiple
adjustment operations may be required to change the iris.
