4 Raise the mirror.
Press the shutter-release
button all the way down.
The mirror will be raised and
the shutter curtain will open,
revealing the low-pass filter.
The display in the viewfinder will
turn off and the row of dashes in the control panel will blink.
5 Examine the low-pass filter.
Holding the camera so that light falls on
the low-pass filter, examine the filter for
dust or lint.
If no foreign objects are
present, proceed to Step 7.
6 Clean the filter.
Remove any dust and lint from the filter
with a blower.
Do not use a blower-
brush, as the bristles could damage the
filter.
Dirt that can not be removed with
a blower can only be removed by Nikon-
authorized service personnel.
Under no circumstances should
you touch or wipe the filter.
7 Turn the camera off.
The mirror will return to the down position and the shutter
curtain will close.
Replace the lens or body cap.
