Aperture Drive in AF (still image)

Changes the aperture drive system to prioritize the auto-focusing tracking performance or to prioritize silence (only when

using a compatible lens).

Menu item details

Standard:

Uses the standard aperture drive system.

Focus Priority:

Changes the aperture drive system to prioritize auto-focusing performance. During continuous shooting using the

electronic shutter, the [Focus Priority] setting allows you to continuously adjust the focus with an F-value greater than

F16.

Silent Priority:

Changes the aperture drive system to prioritize silence so that the sound from the aperture drive is quieter than in

[Standard].

Note

When [Focus Priority] is selected during continuous shooting, sound from the aperture drive may be audible, shooting may

become slower, or the display may flicker. To avoid these phenomena, change the setting to [Standard].

When [Silent Priority] is selected, the focusing speed may become slower, and it may be more difficult to focus on a subject.

The focus is locked to the setting in the first shot when [Aperture Drive in AF] is set to [Standard] or [Silent Priority], and the F-

value is greater than F16.

If [

Shutter Type] is set to [Mechanical Shutter], [Focus Priority] cannot be selected.

During single-shot shooting with [

Shutter Type] set to [Auto], the aperture is driven by the [Standard] system even when

[Focus Priority] is selected.

[Aperture Drive in AF] is unavailable when using a lens incompatible with this function.
