OTHER RECORDING FUNCTIONS
— The camera automatically switches to the Pan
Focus mode (PF) (page 64) whenever you enter
the Movie Mode.
— The camera focuses automatically whenever you
have Auto Focus (page 62) or Macro (
) selected
as the focus mode. Note that the confirmation
tone that sounds during the Auto Focus operation
will be recorded in the audio.If you do not want
confirmation tones in your audio, keep Pan Focus
(PF) as the focus mode, or select Manual Focus
(MF) and manually focus the image before
starting your recording.
— Auto Focus is not performed in the case of the
Pan Focus (PF), Manual Focus (MF) and Infinity
(∞) focus modes, and so no confirmation tone
sounds. In the case of the Manual Focus mode,
you cannot adjust focus settings while recording
is in progress. Be sure to make all adjustments
before beginning the record operation.
— Certain types of memory cards take longer to
record data, which can cause movie frames to be
dropped. 
 and REC flash on the monitor screen
during recording to let you know when a frame
has been dropped.

Adding Audio to a Snapshot
You can add audio to a snapshot after you record it.
• Image Format: JPEG
JPEG is an image format that provides efficient data
compression.
The file extension of a JPEG file is “.JPG”.

• Recording Time:
Up to about 30 seconds per image

 Audio Recording Precautions
• Keep the microphone on the
front of the camera pointed
at the subject.
• Take care that you do not
block the microphone with
your fingers.
• Good recording results are not possible when the camera
is too far from the subject.
• Operating camera buttons during recording can cause
button noise to be included in the audio.
• Pressing the power button or pressing [
] (PLAY) stops
recording and stores any audio recorded up to that point.
• You can also perform “after-recording” to add audio to a
snapshot after recording it, and also change the audio
recorded for an image. See page 109 for more
information.
Microphone
Using the Histogram
You can use the [DISP] button to display a histogram on
the monitor screen. The histogram lets you check exposure
conditions as you record images (page 25). You can also
display the histogram of a recorded image in the PLAY
mode.
Histogram
A histogram is a graph that represents the lightness of an
image in terms of the number of pixels. The vertical axis
indicates the number of pixels, while the horizontal axis
indicates lightness. You can use the histogram to
determine whether an image includes the shadowing (left
side), mid tones (center), and highlighting (right) required to
bring out sufficient image detail. If the histogram appears
too lopsided for some reason, you can use EV shift
(exposure compensation) to move it left or right in order to
achieve better balance. Optimum exposure can be
achieved by correcting exposure so the graph is as close to
the center as possible.

OTHER RECORDING FUNCTIONS
• When the histogram is too far
to the left, it means that there
are too many dark pixels.
This type of histogram results
when the overall image is
dark. A histogram that is too
far to the left may result in
“black out” of the dark areas
of an image.
• When the histogram is too far
to the right, it means that
there are too many light
pixels.
This type of histogram results
when the overall image is
light. A histogram that is too
far to the right may result in
“white out” of the light areas of
an image.
• A centered histogram
indicates that there is good
distribution of light pixels and
dark pixels. This type of
histogram results when the
overall image is at optimal
lightness.
 IMPORTANT! 
• Note that the above histograms are shown for
illustrative purposes only. You may not be able to
achieve exactly the same shapes for particular
subjects.
• A centered histogram does not necessarily
guarantee optimum exposure. The recorded image
may be over-exposed or under-exposed, even
though its histogram is centered.
• You may not be able to achieve an optimum
histogram configuration due to the limitations of EV
shift.
• Use of the flash as well as certain shooting
conditions can cause the histogram to indicate
exposure that is different from the actual exposure of
the image when it was recorded.
• This histogram does not appear when you are using
Coupling Shot (page 75) or Pre-shot (Page 77).

REC Mode Camera Settings
The following are the settings you can make before
recording an image using a REC mode.
• ISO sensitivity
• Grid on/off
• Image Review on/off
• L/R key setting
• Power on default settings
• Resetting the camera
 NOTE 
• You can also configure the settings listed below. See
the referenced pages for more information.
— Size (page 58)
— Quality (page 60)
— White Balance (page 69)
— Digital Zoom (page 52)
— AF Area (page 63)
— Auto PF (page 62)
Specifying ISO Sensitivity
You can change the ISO sensitivity setting for better
images in places where lighting is dim or when you are
using faster shutter speeds.
• ISO sensitivity is expressed in terms of values that
originally indicated the sensitivity to light for photographic
film. A larger value indicates higher sensitivity, which is
better for recording when available lighting is dim.
1.In the REC mode, press [MENU].
2.Select the “REC” tab, select “ISO”, and then
press [].
3.Use [
] and [] to select the setting you want
and then press [SET].

OTHER RECORDING FUNCTIONS
 IMPORTANT! 
• Under certain conditions, a high shutter speed in
combination with a high ISO sensitivity setting can
cause digital noise to appear inside of an image. For
clean, good-quality images, use the lowest ISO
sensitivity setting possible.
• Using a high ISO sensitivity setting along with the
flash to shoot a nearby subject may result in
improper illumination of the subject.
 NOTE 
• You can use the key customization feature (page 89)
to configure the camera so the ISO sensitivity setting
changes whenever you press [] and [] while in the
REC mode.

Specifying Power On Default Settings
The camera’s “mode memory” feature lets you specify the
power on default settings individually for the REC mode,
flash mode, focus mode, white balance mode, ISO
sensitivity, AF Area, digital zoom mode, manual focus
position and zoom position. Turning on mode memory for a
mode tells the camera to remember the status of that mode
when you turn off the camera, and restore it the next time
you turn the camera back on. When mode memory is
turned off, the camera automatically restores the initial
factory default setting for the applicable mode.
The following table shows what happens when you turn
mode memory on or off for each mode.
