Cleaning the low-pass filter

The charge-coupled device (CCD) that acts as the camera’s picture element is fitted with a low-pass filter to prevent moiré. Although this filter prevents dirt from adher- ing directly the CCD, under certain shooting conditions dirt or dust on the filter may appear in photographs. In this case it will be necessary to clean the filter.

Determining Whether the Filter Requires Cleaning

The following two methods are available for determining whether the filter requires cleaning:

1To ensure that the shutter is not damaged, this procedure requires that the cam- era be powered by an EH-4 AC adapter (available separately). Turn the camera off and connect the adapter.
