Technical Notes—Caring for the Camera

The Low-Pass Filter

The image sensor that acts as the camera’s picture element is fitted with a low-pass filter to prevent moiré. Although this filter prevents foreign objects from adhering directly to the image sensor, under certain conditions dirt or dust on the filter may appear in photographs. If you suspect that dirt or dust inside the camera is affecting your photographs, you can check for the pres- ence of foreign objects on the low-pass filter as described below.

1 Turn the camera off and connect an EH-6 AC adapter (available sepa- rately). If you do not have access to an EH-6 AC adapter, take the cam- era to a Nikon-authorized service center.

2 Remove the lens and turn the camera on.

3 Press the button and select Mirror lock-upfrom the setup menu ( 206). The message shown at right will be displayed.

4 Press the multi selector to the right. The mes- sage shown at right will be displayed in the camera monitor, and a row of dashes will be displayed in the control panel and viewfinder. To return to normal operation without raising the mirror, turn the camera off. Mirror lock- up will also be cancelled if the monitor is al- lowed to turn off automatically.

5 Press the shutter-release button all the way down. The mirror will be raised and the shut- ter curtain will open, revealing the low-pass filter, and the row of dashes in the control panel will blink. The displays in the viewfinder and rear control panel will turn off.
