Adjusting the Aperture
60
Momentary Automatic Aperture - Push Auto Iris
Press the PUSH AUTO IRIS button to have the camcorder 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, m 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 m icon next to the aperture
value will disappear.
Exposure Compensation - AE Shift
Use AE shift to compensate the automatic exposure set by the camcorder
using the push auto iris function 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
Alternatively, you can 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 85), you can press the button to adjust the AE
shift level.
When you use the auto push iris function 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.

The Exposure Bar
You can use the exposure bar as a reference when adjusting the aperture or
shutter speed or when compensating the exposure using AE shift. The Î on
top of the exposure bar indicates optimal exposure without any shift (AE±0); the
scale markings indicate the deviation from optimal exposure in 1/2 EV
increments. The indicator inside the exposure bar represents the current
exposure. When the difference between current and optimal exposure is larger
than ±2 EV, the indicator will flash at the edge of the exposure bar. Optimal
exposure will change depending on the light metering mode (A 61) used.
