# Adjusting the Aperture
# Adjusting the Aperture
You can affect the brightness of your recordings or change the depth of field by adjusting the aperture. For
example, use a small aperture value for a shallow depth of field that isolates the subject in focus and nicely blurs
the background. Available aperture values will vary depending on the lens attached to the camcorder.
By default, the camcorder is set to manual aperture but, depending on the lens used, the camcorder offers 3
ways to adjust the aperture. Refer to the list of compatible lenses and functions that can be used (A 191).
Manual aperture: Adjust the aperture value manually using the control dial on the camcorder or on the grip unit,
or remotely, using the Wi-Fi Remote application.
Momentary automatic aperture - Push Auto Iris: During manual aperture, press an assignable button or use the
Wi-Fi Remote application to temporarily adjust the aperture automatically.
Automatic aperture: The camcorder adjusts the aperture automatically.
Required settings on EF Cinema lenses
To adjust the aperture from the camcorder, 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.
Manual Aperture
Using the Control Dial
You can adjust the aperture value of an EF lens using the control dial on the
camcorder or that on the grip unit. You can select the function assigned to
each control dial independently.
By default, both control dials’ function is set to aperture control. If it has
been changed, follow the procedure below to set a control dial’s function to
[Iris] in advance.
To assign aperture control to a control dial
1 Open the [Control Dial] (control dial on the camcorder) or [Grip Ctrl Dial]
(control dial on the grip unit) submenu.
