IMPORTANT!
• You may not be able to achieve the brightness you want when shooting an image 
that is very dark or very bright. If this happens, use the M mode to adjust the 
aperture or shutter speed manually.
• Due to the characteristics of the camera’s semiconductor, slow shutter speeds can 
cause digital noise in images. The camera performs an automatic noise reduction 
process whenever the shutter speed is 1 second or slower. Storage of images shot 
at slower shutter speeds takes longer because of the time required for noise 
reduction. Do not perform any key operation while the image storage operation is in 
progress.
• Due to the characteristics of the imaging element used by the camera, very fast 
moving objects in an image may appear distorted.
• Depending on the shutter speed setting and the recording mode you used, the 
brightness of what appears on the monitor screen when you record the image may 
be different from the brightness of the recorded image.
• Image AS (page 79) does not work in the S mode and M mode. You can, however, 
turn on Camera AS, if you like.
• When recording with some modes, light source flicker can cause horizontal bands 
to appear in the image.
.Pixels
A digital camera image is a collection of small 
dots called “pixels”. The more pixels there are 
in an image, the more detail there will be. 
However, you generally can do with fewer 
pixels when printing an image (L size) 
through a print service, attaching an image to 
e-mail, when viewing the image on a 
computer, etc.

.About image sizes
The size of an image indicates how many pixels it contains, and is expressed as 
horizontal pixelsxvertical pixels.
Image Size Selection Tips
Note that larger images have more pixels, so they take up more memory space.
• For information about image size, image quality, and number of images that can be 
stored, see page 168.
• For information about movie image size, see page 56.
• For information about resizing existing snapshots, see page 102. 8M (3264
x2448) size image = 
Approximately 8 million pixels
*Unit: pixels
VGA (640x480) size image = 
Approximately 300,000 pixels
Large Number 
of PixelsMore detail, but takes up more memory. Best 
when you plan to print large-size prints (such 
as A3 size).
Small Number 
of PixelsLess detail, but takes up less memory. Best 
when you want to send images by e-mail, etc.

pixels) is stored for the JPEG data. RAW image 
data is unprocessed data output by the image 
sensor and is saved in DNG (digital negative) 
format. Though the image of such data is virtually 
undeteriorated, it cannot be viewed on the 
camera’s monitor screen or printed. After 
transferring RAW image data to your computer, 
you can use software that supports the general-
purpose DNG format to process the image and 
convert it to image data that suits your particular 
needs. Since both RAW image data and JPEG 
data are saved by the camera, you can view the 
JPEG version on the camera’s monitor screen.

• The initial factory default image size setting is 9M (9 million pixels).
• Selecting 3:2 (3456x2304 pixels) records images with an aspect ratio of 3:2, which 
matches the standard aspect ratio of print paper.
• The letters “HDTV” stand for “High Definition Television”. An HDTV screen has an 
aspect ratio of 16:9, which makes them wider than the usual 4:3 aspect ratio of 
television screens of the past. Your camera can record images that are compatible 
with the aspect ratio an HDTV screen.
• You should regard the print paper sizes suggested here as guidelines only (200 dpi 
print resolution).
• You can shoot directly to RAW image data only while the t (Single Shot) is 
selected with the Mode dial and “RAW+” is selected as the image size.
• Available image sizes are limited for some functions as noted below.

IMPORTANT!
• The camera will not release the shutter unless the flash unit is raised when any one 
of the following conditions exists. Be sure to raise the flash unit whenever shooting 
with flash is required.
– When shooting with Flash CS, which requires the flash to fire
– When “Flash On” is selected for the flash mode
– When “Auto Flash” or “Red-Eye Reduction” is selected for the flash mode and 
the camera judges that flash is required
NOTE
• Take care to ensure nothing is close to or in contact with the flash unit when it fires. 
Also make sure that the flash unit and the area around it is not dirty. Objects, dust, 
or dirt near the flash unit can be burned when the flash fires.
• Take care so your fingers and the strap do not block the flash.
• The desired effect may not be obtained when the subject is too far away or too 
close.
• Flash charging time depends on operating conditions (battery condition, ambient 
temperature, etc.) With new batteries it takes about 5 seconds.
• Flash charging time and operation are affected by the remaining battery capacity.
The flash will take longer than normal to charge if it is being used when the battery 
level indicator is showing   or   while “Alkaline” is selected for the “Battery 
Type” setting (page 15).
 indicates that the flash is disabled. Replace batteries as soon as possible.
• Shooting with flash turned off when lighting is dim results in a slow shutter speed, 
which can cause image blur due to camera movement. Under such conditions, 
secure the camera with a tripod, etc.
• With red eye reduction, the flash is fired automatically in accordance with 
exposure. It does not fire in areas where lighting is bright.
• The presence of outdoor sunlight, fluorescent lighting, or some other light source 
can cause abnormal image colors.
• Select “Flash Off” for the flash setting when shooting in areas where flash 
photography is prohibited.
• Approximate Flash Range (ISO Sensitivity: AUTO / Recording mode: Single Shot)
Wide Angle: 0.4 m to 7.0 m (1.3 to 23.0)
Telephoto: 1.3 m to 4.4 m (4.3 to 14.4)
*The above values depend on the optical zoom setting.

Red-eye Reduction
Using the flash to shoot at night or in a dimly lit room can cause red spots inside the 
eyes of people who are in the image. This is caused when the light from the flash 
reflects off of the retina of the eye. When red-eye reduction is selected as the flash 
mode, the camera fires a pre-flash to cause the irises in the eyes of any people in the 
image to close, which reduces the chance of red eye.
Note the following important points when using red-eye reduction.
• Red-eye reduction does not work unless the people in the image are looking 
directly at the camera (flash).
• Red-eye reduction may not work very well if the subjects are located far away from 
the camera.
Other Useful Flash Features
• Changing the flash intensity (page 86)
• Compensating for insufficient flash intensity (page 86)

ISO sensitivity is a measure of sensitivity to light.
1.In the REC mode, press [8] .
2.Use [8] and [2] to select the third control panel option from the top 
(ISO Sensitivity).
3.Use [4] and [6] to select the setting you want and then press [SET].
• The current ISO sensitivity setting is used when shooting a High-speed Movie 
in the M (manual exposure) mode. For all other types of movies, “AUTO” is 
used as the ISO sensitivity setting.
•“S Image AS” (page 79) can be used only when the ISO sensitivity setting is 
“AUTO”.
• An ISO setting of ISO 400 or greater is not supported when the “Image Size” 
setting is “RAW+”. If the ISO setting is “ISO 400” or greater when you change 
the “Image Size” setting to “RAW+”, an ISO setting of ISO 200 will be used for 
recording.
You can adjust white balance to match the source of light available where you are 
shooting and avoid the blue cast that results when shooting outdoors when it is 
cloudy, and the green cast that results when shooting under fluorescent lighting.

3.Use [4] and [6] to select the shooting condition you want and then 
press [SET].
• When “‡ Auto WB” is selected for the white balance setting, the camera 
automatically determines the white point of the subject. Certain subject colors 
and light source conditions can cause problems when the camera tries to 
determine the white point, which makes proper white balance adjustment 
impossible. If this happens, select the white balance setting that matches your 
shooting conditions (Daylight, Overcast, etc.)

You can manually adjust an image’s exposure value (EV value) before shooting it.
• Exposure Compensation Range: –2.0EV to +2.0EV
• Unit: 1/3EV
1.In the REC mode, press [8] .
2.Use [8] and [2] to select the fifth control panel option from the top (EV 
Shift).
3.Use [4] and [6] to adjust the exposure compensation value.
To cancel exposure compensation, change 
the EV value to 0.0.
4.Press [SET].
This applies the exposure compensation value. The exposure compensation 
value you set remains in effect until you change it.
NOTE
• When shooting under very dark or very bright conditions, you may not be able to 
obtain satisfactory results even after performing exposure compensation.
Correcting Image Brightness (EV Shift) 
[6]: Increases the EV value. A higher EV 
value is best for light-colored subjects 
and backlit subjects.
[4]: Decreases the EV value. A lower EV 
value is best for dark-color subjects and 
for shooting outdoors on a clear day.
