To Adjust The Amount Of Light (Nd Filter) - Sony NXCAM NEX-FS700U Operating Manual

Adjusting the brightness (Continued)
z Tips
• It is difficult to focus automatically at a lower
shutter speed. Manual focusing with your
camcorder attached to a tripod is recommended.
• When recording under fluorescent lamps,
sodium lamps, or mercury lamps, the picture
may flicker or change colors, or may have
horizontal bands of noise. You may be able to
improve the situation by adjusting the shutter
speed.
• You can switch the shutter speed display
between seconds and degrees ([SHUTTER
DISPLAY], p. 98).
To adjust the shutter speed
automatically
Press the SHUTTER SPEED button G
twice.
The shutter speed value disappears, or
appears next to the shutter speed value.
Setting value when switching

The shutter speed of the same level before
changing the [60i/50i SEL] setting is
applied. See the following table for the

To adjust the amount of light
(ND filter)
If recording conditions are too bright, you
can use ND filter to capture a subject more
clearly.
Set the ND FILTER switch C. 1/4ND
is set to decrease the amount of light
to approximately 1/4, 1/16ND is to
approximately 1/16 and 1/64ND is to
approximately 1/64.
b Notes
• If you switch ND FILTER switch C during
recording, the image or sound may be distorted.
• When the position of the ND FILTER switch
C (CLEAR, 1/4ND, 1/16ND, 1/64ND) is not
detected, flashes on the LCD screen. Make
sure the ND FILTER switch is set to the correct
position.
z Tips
• When shooting a bright subject, diffraction - a
common phenomenon in video cameras, caused
by closing the iris too much - may result in poor
focusing. Using ND FILTER switch C
suppresses this phenomenon for better shooting
images.
