"Noise" (bright spots, randomly-spaced bright pixels, fog, or
●
lines) appears during live view:
•
Randomly-spaced bright pixels, fog, or bright spots may 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.
•
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 live view.
•
In movies, the amount and distribution of randomly-spaced bright
pixels, fog, and bright spots are affected by the option selected for
[Frame size/frame rate] in the movie shooting menu.
•
Note that the distribution of noise in the monitor may differ from
that in the final picture.
Monitor hue changes sharply during live view:
●
Monitor hue may change sharply at high sensitivities (Hi 0.3 to Hi 5)
during burst photography or immediately after the shutter is
released; this does not indicate a malfunction. The display will shortly
return to normal. Pictures taken with the camera are unaffected.
The camera cannot measure a value for preset manual white
●

●

for preset manual white balance.
