The luminance level of artificial lighting—
particularly that of fluorescent lights and
mercury lamps—changes in synchronization
with the power line frequency. Especially in
areas with a power line frequency of 50 Hz, the
vertical sync frequency (approx. 60 Hz) of the
camera recorder and frequency of the lighting
(50 Hz) will interfere with each other, possibly
causing the white balance to change cyclically.
When shooting under artificial lighting or when
adjusting the white balance, set the shutter
speed as shown below.

button are selected alternately.
2
After pressing the SHUTTER button, press
the SPEED SEL button to select the shutter

Each time the SPEED SEL button is
pressed, the shutter speed changes by one
setting in the following sequence.
O
The higher the shutter speed, the lower
the sensitivity of the camera.
O
When the iris is controlled automatically, it
opens more and more and the depth of
focus becomes shallower and shallower
as the shutter speed increases.

Synchro scan
The shutter speed of synchro scan used when
shooting TV screens or computer monitor
screens is set using the SYNCHRO SCAN item
on the setting menu CAMERA SETUP screen.
(See page 38)
O
When the shutter is adjusted to suit the
frequency of a TV screen or computer
monitor screen, the horizontal noise that
occurs when shooting TV screens is
minimized.
If a setting other than OFF has been selected for the OTHER
DISPLAY item on the setting menu DISPLAY SETUP screen,
the current shutter speed setting is displayed in the viewfinder
and on the LCD monitor. However, it is not displayed if the
standard (OFF) shutter speed has been set.
