[Wind filter]
When set to [Enable], it reduces wind noise when there is wind
outdoors. This feature takes effect only with the built-in
microphone.
Note that [Enable] will also reduce low bass sounds, so set this
function to [Disable] when there is no wind. It will record a more
natural sound than with [Enable].
[Attenuator]
Even if you set [Sound recording] to [Auto] or [Manual] and
shoot, sound distortion may still result if there is a very loud sound.
in such a case, setting it to [Enable] is recommended.
[] _ In BaSiczone modesl the Settings available for [sound recording] Will
be [0B/Off], !f [on] is set, the sound-recording !eye! will be adjusted
automatically (same as w!th [Auto]). However, the wind filter function will
not take effect.
