4.8.5 Optical filter selection
A neutral density filter and a special effect filter can be placed in the path of the optical
signal to modify the incoming light. The filters are selected via the
Filter switches (1)
at the top-front of the camera. These filters can be used, for example, to control depth
of field or exposure levels.

Note
Some camera versions only have the neutral density filterwheel.

The camera does not need colour optical filters to be able to white balance correctly.
The range of the auto-white balance is so wide (from 2.5K to 20K) that there is never
any need to use colour filters to obtain the correct white. Rotate the switches to move
the optical filter wheels.
The outer (bigger) filter switch has four positions:
The inner (smaller) filter switch also has four positions:
The status of the filter wheels is displayed in the viewfinder for a few seconds. The ND/
RE indicator (29) in the viewfinder lights when an ND (Neutral Density) filter is
selected.
4.8.6 Colour temperature selection
For true colour reproduction the ambient lighting conditions must be compensated for
by selecting a value for the colour temperature. The standard file setting is 3200K
(normally used for tungsten light). Two other reference colour temperatures are
available; 5600K (for outdoors, clouded conditions) and 7500K (for outdoors, clear
blue skies).
