● Shooting ends unexpectedly or does not start:
Shooting may end automatically to prevent the camera overheating, for example if:
- the ambient temperature is high,
- the camera has been used for extended periods to record videos, or
- the camera has been used in continuous release modes for extended periods.
If pictures cannot be taken because the camera is running hot, turn the camera off and wait for
it to cool before trying to take pictures again. Note that the camera may feel warm to the touch,
but this does not indicate a malfunction.
● Image artifacts appear in the display during shooting:
To reduce noise, adjust settings such as ISO sensitivity, shutter speed, or Active D-Lighting.
At high ISO sensitivities, noise may become more noticeable in long exposures or in pictures
recorded when the camera temperature is elevated.
Randomly-spaced bright pixels, fog, or bright spots may arise as a result of increases in the
temperature of the camera's internal circuits. Turn the camera off when it is not in use.
Randomly-spaced bright pixels, fog, lines or unexpected colors may appear if you press the X
button to zoom in on the view through the lens during shooting.
Note that the distribution of noise in the display may differ from that in the final picture.
This issue can sometimes be addressed by checking and optimizing the image sensor. Perform
pixel mapping using [Pixel mapping] in the setup menu.
● The camera cannot measure a value for preset manual white balance:
The subject is too dark or too bright.
● Certain pictures cannot be selected as sources for preset manual white balance:
Pictures created with cameras of other types cannot serve as sources for preset manual white
balance.
● White balance (WB) bracketing is unavailable:
White balance bracketing is not available when an NEF (RAW) or RAW + JPEG/HEIF option is
selected for image quality.
White balance bracketing cannot be used in multiple exposure and HDR overlay modes.
