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.
5.7 Exposure
5.7.1 Exposure time
The exposure time values of 1/200 s, 1/500 s and 1/1000 s are used to capture fast moving
objects so that these can be played back sharply in slow motion. The value selected depends
on the speed of the moving object.

Note
Decreasing the exposure time lowers the camera’s sensitivity proportionally.
Press the EXP. TIME button and select the

function. Select the exposure time you
want to use.
On the left side panel of the camera the momentary up/down exposure time switch gives a
choice of exposure time presets.
