# Adjusting the Aperture
NOTES
• When using an EF lens with no lens contacts or most EF Cinema lenses*, you cannot adjust the aperture using
the camcorder. Adjust the aperture using the lens.
* Select EF Cinema lenses (A 191) support iris adjustment from this camcorder.
• When 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 activate this correction.
• When an optional RC-V100 Remote Controller is connected to the camcorder, you can adjust the aperture
with the remote controller’s IRIS dial. By default, turn the dial right to open up the aperture (smaller F value) and
left to close the aperture (larger F value).
• When using an EF Cinema lens compatible with iris adjustment from the camcorder, when you change the
aperture value from a position of fully open or fully closed iris, multiple adjustment operations may be required
until the aperture changes.
Momentary Automatic Aperture - Push Auto Iris
During manual aperture, you can use the push auto iris function to have the camcorder temporarily take control
and automatically adjust the aperture (f/stop) for an optimal exposure.
Using an Assignable Button
To use the push auto iris function, you must first set an assignable button to [PUSH AUTO IRIS] in advance.
1Set [~ Camera Setup] > [Iris] > [Mode] to [Manual] (A 70).
• This is only necessary when using a lens compatible with automatic aperture. For other lenses, [Manual] is
the default setting and cannot be changed.
• When using a compatible EF Cinema lens, enable automatic adjustment on the lens (A 69).
2 Set an assignable button to [PUSH AUTO IRIS] (A 113).
3 Press and hold the assignable button.
• The camcorder will automatically adjust the aperture to obtain optimal exposure. As long as you hold the
assignable button pressed down, will appear on the screen next to the aperture value.
• When you release the assignable 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.
