This section covers the settings for electronic shutter
speed and the clear scan function.
Shutter speeds
There are five shutter speeds, from '/100 s (NTSC) or
"feo s (PAL) to '/2000 5. Increasing the shutter speed
teduces blurring when shooting a fast-moving subject.
It is also possible to reduce flicker when shooting
under fluorescent lighting by changing the shutter
speed.
Clear scan function
When shooting a computer screen or projected image,
horizontal bands may appear in the camera image.
This is because the vertical scan frequency of the
computer-generated image is different from the
vertical scan frequency of the video system. The clear
scan function allows you to select a vertical scan
frequency to reduce this interference.
Setting the shutter speed and clear scan
function
Notes on setting the shutter speed
If the EVS function setting in the advanced menu is
ON, it is not possible to change the shutter speed.
© The faster you make the shutter speed, the darker the
image becomes. Check the brightness in the
viewfinder, and if necessary increase the lighting
level or adjust the iris.
© When the shutter speed is very fast, shooting a high
intensity subject may cause long vertical tails to
appear on the highlights (smear).
Note on setting the clear scan function
The vertical scan frequencies of computer screens
vary, and it may not be possible to eliminate the
interference patterns entirely. Note also that the
vertical scan frequency may change depending on the
software being run.
1 Set the SHUTTER switch to the ON position.
The SHUTTER indicator in the viewfinder comes
on, and it is now possible to make the shutter speed
or clear scan function setting.

select the required shutter speed or scan frequency.
Each time you press the UP/ON button or DOWN/
OFF botton, the shutter speed or clear scan
frequency setting changes in the following order:
4/100 (NTSC)
(Value when shipped) 1/250 <—* 1/500 «—-» 1/1000 «— 1/2000:

200.3Hz - . . 60.4Hz (NTSC)
201.4Hz- - - 60.3Hz (PAL)
When using the clear scan function
Watching the monitor screen, adjust the frequency
to give minimum interference.
If there is a black band in the monitor image,
reduce the frequency, and if there is a white band,
increase the frequency.
The new value for the shutter speed or clear scan
frequency remains set until changed, even when
the camera is powered off.
