5.8 Exposure time
The exposure time values of 1/200, 1/500 and 1/1000 of a second 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.

Increasing the exposure speed lowers the camera’s sensitivity proportionally.
5.8.1 Selecting the exposure time
The momentary up/down Exposure time switch gives a choice of exposure time settings. If
an exposure time other than nominal is selected, the Non-standard indicator (!) in the
viewfinder lights.
5.8.2 Lighting
The exposure selection also includes lighting control positions which can be used when
shooting with lighting that is operating at a different frequency to the camera. There are two
positions; 50 Hz and 60 Hz. Each of these positions can be varied further in a range from -10 to
+10 Hz. To reduce flicker select the frequency closest to the frequency of the lights and then
vary the lighting control in the
INSTALL
menu to obtain the best result.
