286 Technical Notes

: Clean front and rear lens elements. If 

problem persists, clean the image sensor manually (

Nikon-authorized service representative.

quality (

: Live view may end automatically 

to prevent damage to the camera’s internal circuits if:
• The ambient temperature is high
• The camera has been used for extended periods in live view or to 

record movies

• The camera has been used in continuous release modes for extended 

periods. If live view does not start when you attempt to start live view, 
wait for the internal circuits to cool and then try again. Note that the 
camera may feel warm to the touch, but this does not indicate a 
malfunction.

: “Noise” (randomly-spaced bright 

pixels, fog, or lines) and unexpected colors may appear if you zoom in on 
the view through the lens (

0 38) during live view; in movies, the amount 

and distribution of randomly-spaced bright pixels, fog, and bright spots 
are affected by frame size and rate (

0 141). Randomly-spaced bright 

pixels, fog, or bright spots may also arise as a result of increases in the 
temperature of the camera’s internal circuits during live view; exit live 
view when the camera is not in use.

: Choose an option 

for Flicker reduction that matches the frequency of the local AC power 
supply (

: A flashing sign, flash, or 

other light source with brief duration was used during live view or movie 
recording.
