a14: Maximum Aperture Lv

G button U A Custom Settings menu

When set to [On], the shooting display in the viewfinder or monitor is always displayed with the maximum aperture. When you press the shutter-release button all the way down, the aperture will adjust to the configured aperture value before shooting.

Cautions: When “Maximum Aperture Lv” Is Set to “On”

The lens will always be at maximum aperture regardless of aperture setting. Avoid pointing the camera at the sun or other powerful light sources. Failure to observe this precaution could damage the camera’s internal circuitry.
The timing of the shutter release may be slightly delayed. Shutter release timing delays are more likely to occur when [Silent mode] is set to [ON] in the setup menu.
Flickering may appear on the shooting display under the following conditions:
- just before or after the shutter is released, or
- when pressing a control assigned the role of [Preview] in Custom Setting f2 [Custom controls (shooting)].
