desired setting.
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.
