Smudges appear in photographs:

･
Is there foreign matter on the image sensor? See “Manual cleaning”
(

Bokeh is irregular:
●
With fast shutter speeds and/or fast lenses, you may notice irregularities in
how
Bokeh is shaped. The effect can be mitigated by choosing slower
shutter speeds and/or higher f-numbers.
Pictures are affected by noticeable ghosting or flare:
●
You may notice ghosting or flare in shots that include the sun or other
bright light sources. These effects can be mitigated by attaching a lens
hood or by composing shots with bright light sources well out of the
frame. You can also try such techniques as removing lens filters, choosing
a different shutter speed, or using silent photography.
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
- The camera has been used in continuous release modes for extended
periods
･
If photographs cannot be taken because the camera is running hot, turn
the camera off and wait for it to cool before trying to take photographs
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.
