or
1
/
100
second.
When the frequency is 60 Hz
Set the shutter speed to
1
/
60
or
1
/
120
second.
Using the flicker-reduction function
Set “Mode” of “Flicker Reduce” (page 120) on
the CAMERA SET menu to “Auto” or “On” and
set “Frequency” to the power-supply frequency
(50 Hz or 60 Hz).

the power-supply frequency, flicker may not be
reduced sufficiently even if you activate the
flicker-reduction function. In such cases, use the
electronic shutter.

• It is recommended to set “Mode” to “Off” when
shooting outdoors or under lighting that does
not cause flicker. (It can be also “Auto,” but the
compensation may not be done properly.)
• It is recommended to set “Mode” to “Auto”
when shooting indoors or under various lighting
that may cause flicker, such as fluorescent,
sodium, or mercury-vapor lamps. (If
continuously shooting under lighting that may
cause flicker, “Mode” should be set to “On.”)
The recommended “Mode” settings are shown
below.
