Built-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.
C Effects 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.
