Use in situations such as when overexposure results from the subject being too bright. Y Z k Option On Auto Off (default setting) Description Use the ND filter to reduce the light. In mode A (programmed auto), reduce the light automatically with the ND filter according to the brightness of the subject. • In shooting modes B, C and D, the ND filter becomes Off even if this option is selected. The ND filter is not used. 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 small 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 by three steps, the speed can be changed to 1/250 second without changing the aperture value.
