Caring for the Camera
Cleaning the Low-Pass Filter Manually
If image sensor cleaning (A 160) is unable to completely remove dirt or dust from the
filter, you can clean the filter as described below. Note, however, that the filter is extremely
delicate and easily damaged. Nikon recommends that the filter be cleaned only by Nikon-
authorized service personnel. To prevent the camera from powering off while the mirror is
raised, use a fully-charged battery or an optional AC Adapter EH-5a with a Power
Connector EP-5 (A 156).
1
Turn the camera off and remove the lens, and turn the camera on.
Do not turn the camera on until after the lens has been removed.
2
Select Mirror lock-up from the setup menu.
Note that this option is not available at battery levels of W or below.
3
Highlight On and press OK.
The message shown at right will be displayed. To restore normal
operation without inspecting the low-pass filter, turn the camera off.
4
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.
5
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.
B
Use a Reliable Power Source
The shutter curtain is delicate and easily damaged. If the camera turns off with the mirror raised, the
curtain will close automatically. To prevent damage to the curtain, observe the following
precautions:
• Do not turn the camera off until cleaning or inspection is complete. Do not remove or disconnect
the power source while the mirror is raised.
• If the battery runs low while the mirror is raised, a beep will sound and the AF-assist illuminator will
blink to warn that the shutter curtain will close and the mirror will be lowered after about two
minutes. End cleaning or inspection immediately.
