can be placed in the path of
the optical signal to modify the incoming light. These filters can be used, for example, to
control depth of field or exposure levels.
Press the FILTERS button and select the filter type you want to change:
ND
or
FX
. Use the
navigation buttons to step through the ND and FX filters.
On the camera, press the Filter button on the left side panel of the camera. The Filters menu is
shown in the viewfinder. Navigate to the filter type (ND or FX, when available) and select the
filter from the list.

Note
The camera does not need color optical filters to be able to white balance correctly. The range
of the auto-white balance is so wide (from 2500 K to 20000 K) that there is never any need to
use color filters to obtain the correct white balance.
