5.4.3 Digital noise reducer
Although the CMOS imagers of the camera have low noise, circumstances may require extra
video noise reduction. To do this, a user-definable digital noise reducer is available. In the
VF
menu, go to the
VIDEO
menu and select the
NOISE REDUCTION
item.
Select one the presets 1 , 2 , 3 or 4 or Off to turn off the noise reducer. Preset 1 produces the
lowest noise reduction while preset 4 produces the highest. Try and select the best option for
your situation.

High noise reduction may introduce unwanted artifacts in the image.
5.5 Optical filters
A neutral density and an effect filter can be placed in the path of the optical signal to modify the
incoming light. The filter is selected via the
Filter switch at the top-front of the camera. The
filter can be used, for example, to control depth of field or exposure levels.
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. Rotate the switch to move the optical filter wheel.
The filter switch has four positions:
