With artificial lighting and especially fluorescent 
lights and mercury-vapor lamps, the luminance 
changes in synchronization with the power 
line frequency. When this frequency is 50 Hz, 
mutual interference will occur between the 
camerarecorder’s vertical sync frequency (approx. 
60 Hz) and the lighting frequency (50 Hz). This 
means that the white balance may change 
periodically.
Before shooting in areas with artificial lighting or 
adjusting the white balance, set the shutter speed 
as follows.
Progressive 
mode
Shutter speed
50 Hz
60 Hz
OFF (60i)
1/100
OFF (1/60)
30P
OFF (1/50)
1/60
24P/24PA/
24PN
OFF (1/50)
1/60
The gain is fixed at 0 dB with a shutter speed of 
1/12 and 1/15.
Synchro scan
Set the shutter speed of the synchro scan (used 
when shooting a television or computer monitor) in 
the setup menus, SCENE FILE screen, SYNCRO 
SCAN. (Page 98)
Adjust the shutter speed to match the frequency 
of the television or computer monitor to minimize 
the horizontal noise that appears when shooting 
such subjects.
By switching to progressive mode you can also 
shoot PAL system television screens.
When the OPERATION TYPE option in the 
SCENE FILE screen (page 98) is set to FILM 
CAM, the shutter opening angle can be adjusted 
from 10° to 360° in 0.5° steps.
Example: When the recording frame rate is set to 
24 fps and the exposure time is halved, 1/24÷2 = 
1/48 = 180° (1/24 = 360°)
In the default setting (180°), this becomes 1/2 of 
the exposure time. If it were 90°, it would be 1/4, 
and if it were 45°, it would be 1/8 of the exposure 
time.
(Shutter opening angle: This is equivalent to the 
shutter speed of a film camera, and a wider angle 
results in a longer exposure to light.)
If the shutter speed is displayed in blue 
characters followed by (1/60), you cannot change 
the shutter speed in the blue characters while the 
current recording format is used. The speed is 
fixed at (1/60).
You can change the progressive mode in 
the setup menu with REC FORMAT in the 
RECORDING SETUP screen. (Page 104)
