You can manually adjust the iris to control
the volume of the light entering the lens. By
adjusting the iris, you can change or close
the aperture of the lens, which is expressed
as an F value between F1.6 and F11. The
volume of the light increases the more that
you open the aperture (decreasing F value).
The volume of the light decreases the more
that you close the aperture (increasing F
value). The current F value appears on the
screen.
1 During recording or standby, set the
AUTO/MANUAL switch F to
MANUAL.
2 Set the IRIS switch B to MAN.
3 Adjust the iris with the iris ring C.
During the manual iris adjustment, you
can temporarily return to the auto iris
adjustment while holding down the
PUSH AUTO button A.
z Tips
• The F value becomes close to F2.0 as the zoom
position changes from W to T even when you
open the aperture by setting the F value lower
than F2.0, such as F1.6.
• The range of focus, an important effect of the
aperture, is called the depth of field. The depth
of field gets shallower as the aperture is opened,
and deeper as the aperture is closed. Use the
aperture creatively to obtain the desired effect in
your photography.
• This is handy for making the background
blurred or sharp.
To adjust the iris automatically
Set the IRIS switch B or
AUTO/MANUAL switch F to AUTO.
b Notes
• When you set the AUTO/MANUAL switch F
to AUTO, other manually adjusted items (gain,
shutter speed, white balance) also become
automatic.
.
You can record the subject clearly by using
the ND filter D when the recording
environment is too bright. If you do not
want to reduce the volume of light, use the
ND filter 1. The ND filters 2, 3 and 4
reduce the volume of light to about 1/4,
1/16 and 1/64, respectively.
If the ND icon flashes during the iris
automatic adjustment, set the ND filter D
to the position that the icon indicates. The
ND icon does not flash during the manual
iris adjustment.
b Notes
• If you change the ND filters D during
recording, the movie and sound may be
distorted.
• will flash when your camcorder cannot
detect the ND filter positions (1/2/3/4). Check
the ND filter position.
