[Flicker Reduction]
Setting [On] automatically detects and corrects flickering from fluorescent lights.
Note
• Erroneous flicker detection may cause horizontal noise. In this case, avoid using [Flicker Reduction].
• When the frame frequency is 23.98 Hz, the flicker reduction setting would not be effective.
• When shooting under an artificial light source such as a fluorescent lamp, mercury lamp, or halogen light, flicker may occur in principle
depending on the shutter speed set. It may be possible to suppress flicker by setting the shutter speed according to the frequency of the
power supply. For 50 Hz, select 1/50 second* or 1/100 second; for 60 Hz, select 1/60 second or 1/120 second.
* Not available depending on the frame frequency.
[Auto S low S hutter]
When shooting in a place with insufficient light (such as a room with low light), slows down the shutter speed automatically
and adjusts to make the video brighter.
Possible to set when the shooting mode is (Full Auto) and (Program AE).
Note
• The slowest shutter speed for each frame frequency differs as follows.
At 23.98 Hz: 1/12 sec.
At 29.97 Hz: 1/15 sec.
At 59.94 Hz: 1/30 sec.
At 25.00 Hz: 1/12 sec.
At 50.00 Hz: 1/25 sec.
• Auto slow shutter cannot be used under the conditions below.
– When AGC limit is enabled
– When frame frequency is 23.98 Hz, 29.97 Hz, or 25.00 Hz, and [Focus] > [Face Detection AF] is [Face Det. & Tracking] or [Face Only]
• For the precautions when shooting with auto slow shutter, refer to the following section "About Shooting with Slow Shutter".

About Shooting with Slow Shutter
By setting the [Shooting Mode] to (Manual Exposure) or (Shutter Priority AE) to set a slow shutter
speed, setting it to (Low Light), or setting the [Auto Slow Shutter] to [ON], it is possible to shoot the subject
brightly even where the light is insufficient. However, depending on the scene or the subject, the following may occur.
– Noticeable residual image from moving subjects
– Deterioration of image quality
– White spots on the screen
– Autofocus not functioning well
