Shooting images with

Changing IRIS parameter changes the
range that is in focus.

[ Manual Settings]  [IRIS]
 [Manual].
2
Select / to adjust the iris.
As the F-value becomes smaller, the iris
opens and the background blurs.
To change the atmosphere of image
by the IRIS parameter
Smaller F-value (opening the iris) narrows
the range that is in focus. Larger F-value
(narrowing down the iris) widens the range
that is in focus. Open the iris to blur the
background, or narrow down the iris to
sharpen the whole image.
Notes
Even if you open the IRIS wider (a smaller
F-value) than F3.4 when you set the zoom lever
to the W (Wide angle) side, the IRIS is reset
to F3.4 as you move the zoom lever to the T
(Telephoto) side.

Shooting images with
the Shutter Speed
priority mode
You can express the movement of a moving
subject in various way by adjusting the
shutter speed. When shooting a mountain
stream, for example, a splash of water will
be captured clearly with high speed shutter,
or a trailing image of water with low speed
shutter.
1
Select  [Camera/Mic]
 [ Manual Settings] 
[Shutter Speed] [Manual].
2
Select / to adjust the
shutter speed.
As the value becomes smaller (slower
shutter speed), a trailing image of the
movement of the subject is captured.
Notes
When you record images under a fluorescent
lamp, sodium lamp, or mercury lamp,
horizontal stripes may appear, flicker may
occur, or color may change. In this case, change
the shutter speed according to the power supply
frequency in your region.
