Troubleshooting

Battery and power source
When I shake the camera, I hear a rattling sound from the camera.

• The sound is caused by the In-Body Image Stabilizer. This is not a malfunction.

The camera cannot be operated even when it is turned on.
The camera turns off immediately after it is turned on.

• The battery is exhausted. Charge the battery.

This unit is turned off automatically.
• [Economy] is enabled.

The battery becomes flat too quickly.
• When [6K/4K Pre-Burst] or [Pre-Burst Recording] is set, the battery drains faster.
> Use these functions only when recording with them.
• Is a Wi-Fi connection being used for a long period of time?
The battery can become flat quickly when connected to Wi-Fi.
> Turn the camera off frequently by using the [Economy] etc.

Recording
Taking pictures is not possible.
The shutter will not operate immediately when the shutter button is pressed.

• Is [Focus/Release Priority] in the [Custom] menu set to [FOCUS]?
You cannot take a picture until the subject is brought into focus.

The recorded picture is whitish.
• Picture might look whitish when lens or image sensor gets dirty with fingerprints or similar.
> If the lens is dirty turn the camera off and then gently wipe the lens surface with a soft, dry
cloth.
The recorded picture is too bright or dark.
• Is the AE Lock applied incorrectly?

Multiple pictures are taken at one time.
• Check the drive mode setting.
• Are you using the bracket function?

The subject is not focused properly.
• The subject is beyond the focus range of the camera.
• Is [Shutter AF] in the [Custom] menu set to [OFF]?
• Is [Focus/Release Priority] in the [Custom] menu set to [RELEASE]?
• Is the AF Lock applied incorrectly?

The recorded picture is blurred.
The Image Stabilizer is not effective.

• The shutter speed will become slower and the Image Stabilizer function may not work properly
when taking pictures especially in dark places.
> We recommend using a tripod and the self-timer when taking pictures with a slow
shutter speed.

The recorded picture looks rough.
Noise appears on the picture.

• Try the following:
> Decrease the ISO sensitivity.
> Increase the setting for [Noise Reduction] in [Photo Style] or lower the setting for each of
the items other than [Noise Reduction].
> Set the [Long Shtr NR] to [ON].

The subject appears distorted on the picture.
• If you record a moving subject when using the electronic shutter or recording motion picture or
a 6K/4K photo, the subject may appear distorted on the picture. This is characteristic of MOS
sensors which serve as the camera’s pickup sensors. This is not a malfunction.

Striping or flicker may appear under lighting such as fluorescent lighting and
LED lighting fixture.

• This is characteristic of MOS sensors which serve as the camera’s
pickup sensors.
This is not a malfunction.
• When using the electronic shutter, lowering the shutter speed
may reduce the effect of the horizontal stripes.
• If noticeable flicker or striping is seen under lighting such as a
fluorescent or LED lighting fixture when recording motion pictures, you can reduce the flicker or
striping by setting up [Flkr Decrease] and fixing the shutter speed. It is possible to select
a shutter speed from [1/50], [1/60], [1/100], or [1/120]. You can set the shutter speed manually
in the Creative Video Mode.

Stripes appear in high ISO sensitivity.
• Stripes may appear in high ISO sensitivity or depending on the lens you use.
> Decrease the ISO sensitivity.

The brightness or the hue of the recorded picture is different from the actual
scene.
• When recording under fluorescent or LED lighting fixture, etc., increasing the shutter speed
may introduce slight changes to brightness and color. These are a result of the characteristics
of the light source and do not indicate a malfunction.
• When recording subjects in extremely bright locations or recording under fluorescent lighting,
LED lighting fixture, mercury lamp, sodium lighting, etc., the colors and screen brightness may
change or horizontal striping may appear on the screen.

Bright spot not in subject is recorded.
• There may be defective pixels in the image sensor.
> Perform [Pixel Refresh] .

Motion pictures
Recording motion pictures is not possible.

• If you continue to use the same card after changing [System Frequency], motion
pictures may not be recorded. To record with the same card, reset [System Frequency] to the
original setting. To record motion pictures with the current setting, try the following:
– Perform formatting on this unit after saving necessary data on a PC, etc.
– Insert a different card.
• You may not be able to record for a short while after turning this unit on when using a large
capacity card.

Motion picture recording stops in the middle.
• When the ambient temperature is high or motion picture is recorded continuously, the camera
may display [ ] and stop the recording to protect itself. Wait until the camera cools down.
• Depending on the [Rec Format] and [Rec Quality] of a motion picture, the speed class rating
required for the card differs. Use a card that meets the rating. (“Recording of motion pictures/6K
photos/4K photos and speed class ratings”)

Sometimes it is difficult to focus with Auto Focus when recording 4K motion
pictures.

• This phenomenon occurs when the camera is trying to record with highly accurate focus at a
reduced Auto Focus speed, and is not a malfunction.

In motion pictures, abnormal clicking and buzzing sounds are recorded.
The recorded sound is very quiet.

• With recording in a quiet environment, depending on the lenses used, the sound of aperture
and focus actions may be recorded in motion pictures.
Focus operation can be set to [OFF] in [Continuous AF]
• While recording motion pictures, plugging the aperture of the microphone with a finger may
reduce the level of audio recording or audio may not record at all. Also be careful because the
operation sound of lenses can easily be recorded at this time.

An operation sound is recorded in a motion picture.
• We recommend recording in Creative Video Mode if you are concerned about operational
sounds.

Flash
The flash is not activated.

• When the electronic shutter is used, the flash is not activated.
• When [Silent Mode] is set to [ON] , the flash is not activated.

Even when the camera is put in sleep mode, the external flash does not enter
sleep mode.
Even when the camera is turned off, the external flash does not turn off.

• When [Sleep Mode], [Sleep Mode(Wi-Fi)], or [Power Save LVF Shooting] is activated,
the external flash may not enter sleep mode automatically. When the camera is turned off, the
external flash may not turn off automatically.
> In such cases, turn off the external flash manually.

Monitor/Viewfinder
The Monitor/Viewfinder turns off although the camera is turned on.

• If no operations are performed during the set time period, [Auto LVF/Monitor Off] is
activated, and the Monitor/Viewfinder turns off.
• When an object or your hand is positioned near the eye sensor, the Monitor display may switch
to the Viewfinder display.

It may flicker for an instant or the brightness of the screen may change
significantly for an instant.

• This occurs due to the aperture of the lens changing when the shutter button is pressed
halfway, or when the brightness of the subject changes. This is not a malfunction.

Monitor and viewfinder do not switch when [LVF] is pressed.
• It is only displayed on the monitor when the camera is connected to a PC or printer.

Unevenly bright parts or irregular colors appear on the Viewfinder.
• Viewfinder of this unit adopts OLED. Screen burn-in may occur on the screen/viewfinder when
a same image is displayed for a long period of time, but it does not affect the recorded images.

The color tone of the viewfinder differs from the actual tone.
• Being a characteristic of the viewfinder of this unit, this phenomenon is not a problem.
Recorded images are not affected.

Playback
The picture is not played back.
There are no recorded pictures.
