[Wind filter]
If [Enable] is set, outdoor wind noise entering the microphone will
be reduced. Note that, some low-tone noise might also be
reduced. When shooting in places where there is no wind, set this
to [Disable] for a more natural sound recording.
The sound volume balance between L (left) and R (right) cannot be
adjusted.
The 48 kHz sampling frequency will be 16-bit recordings for both L and R.
Silent shooting
This function applies to still photo shooting (p.159).
Metering timer
You can change how long the exposure setting is to be displayed
(AE lock time) when the <A> is pressed.
