Adjusting the Aperture
NOTES
• When using an EF lens with no lens contacts, such as a Canon Cinema lens, you cannot adjust the aperture
using the camcorder. Adjust the aperture using the lens.
• You can use the [w Other Functions] > [Custom Function] > [Grip Ctrl Dial Dir.] setting (A 99) to change
the direction of the adjustment when you turn the control dial.
• If you are using an EF lens that can correct the aperture value according to the position of the zoom, you can
use the [~ Camera Setup] > [Iris] > [Zoom-Iris Correct.] setting to select whether to maintain the f/stop as
you zoom.
• If you set an assignable button to [Iris +] or [Iris -] (A 87), you can press the button to respectively open up or
close the aperture.
Momentary Automatic Aperture - Push Auto Iris
During manual aperture, you can press the PUSH AUTO IRIS button to have
the camcorder temporarily take control and automatically adjust the aperture
(f/stop) for an optimal exposure.
Hold down the PUSH AUTO IRIS button.
• The camcorder will automatically adjust the aperture to obtain optimal
exposure. As long as you hold the button pressed down, will appear on
the screen next to the aperture value.
• When you release the button, the selected f/stop will be set as the aperture
value. Automatic aperture mode will end and the icon next to the aperture
value will disappear.
Exposure Compensation - AE Shift
Use AE shift to compensate the exposure that was set using automatic
aperture, in order to darken or lighten the image. You can select from 15
available AE shift levels.
1 Open the [AE Shift] submenu.
[~ Camera Setup] > [AE Shift]
2 Select an AE shift level and then press the joystick.
Available AE Shift Levels
NOTES
• You can also set the AE shift level by turning the control dial while holding the PUSH AUTO IRIS button
pressed down.
• If you set an assignable button to [AE Shift +] or [AE Shift -] (A 87), you can press the button to adjust the AE
shift level.
• When you use automatic aperture (including push auto iris) after setting an AE shift level, the camcorder will try
to adjust the aperture (f/stop) so as to achieve the AE shift level that was set rather than optimal aperture.
