Rotate the mode dial to A, B, C, D, E, For NMdbutton MA, B, Cor Dtab (A10) MBuilt-in ND filter

When the camera's built-in ND filter is used, the amount of light that enters the camera can be reduced to about one-eighth (equivalent to three steps lower in terms of the exposure value) while shooting. Use in situations such as when overexposure results from the subject being too bright.

Option	Description
On	Use the ND filter to reduce the light.
Off (default setting)	The ND filter is not used.

The icon for the current setting other than Off is displayed on the monitor (A12).

CEffects of the Built-in ND Filter

Using the filter may enable the shooting of subjects that are too bright without overexposing the image. It can also be used in situations such as when you want to slow down the shutter speed at a low aperture value.

For example, at a shutter speed of 1/2000 second with the correct exposure, if the ND filter is used to reduce the light in three steps, the speed can be changed to 1/250 second without changing the aperture value.
