“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

• Randomly-spaced bright pixels, fog, lines or unexpected colors may
appear if you press the
X ( T ) button to zoom in on the view

pixels, fog, and bright spots are affected by the option selected for

• Note that the distribution of noise in the monitor may differ from
that in the final picture.
