31Quick Start Basics
Operation
• Never open the battery cover while the back lamp is flashing green. Doing so can 
result in the image you just shot being sa ved incorrectly, damage to other images 
stored in memory, malfunction of the camera, etc.
• If unwanted light is shining directly ont o the lens, shade the lens with your hand.
Monitor Screen when Shooting Snapshots
• Subject brightness conditions can cause monitor screen response to slow and can 
cause digital noise in the monitor screen image.
• The image that appears on the monitor screen is for image composition. The actual 
image will be recorded at the quality set for the image quality setting (page 101).
Shooting Indoors under  Fluorescent Lighting
• Minute flickering of fluorescent lighting  can affect the brightness or color of an 
image.
Other Precautions
• Due to the characteristics of the camera ’s semiconductor, slow shutter speeds can 
cause digital noise in images. The came ra performs an automatic noise reduction 
process whenever the shutter speed is 1 se cond or slower. Storage of images shot 
at slower shutter speeds takes longer bec ause of the time required for noise 
reduction. Do not perform any key operati on while the image storage operation is in 
progress.
• A noise reduction process is performed when  ISO sensitivity is set to a high value. 
This can cause the camera to take relative ly longer to be ready to shoot again after 
you press the shutter button. Do not perform any key operation while the image 
recording operation is in progress.
• Due to the characteristics of the imagi ng element used by the camera, very fast 
moving objects in an image may appear distorted.
Snapshot Shooting Precautions 
						

							
32Quick Start Basics
• Any of the following can make proper focus impossible.– Solid color wall or other very low contrast subject
– Strongly back lit subject
– Very shiny subject
– Blinds or other subject with  a repeating horizontal pattern
– Multiple subjects at varyin g distances from the camera
– Subject in a dark location
– Subject that is too far away for light  from the AF assist light to reach
– Camera movement while shooting
– Fast-moving subject
– Subjects outside the focus range of the camera
• If you cannot focus properly, try using  focus lock (page 54) or Manual Focus (page 
52).

Selecting a Recording Mode
Your camera has a variety of 
different recording modes. Before 
shooting, use the mode dial to 
select the recording mode that suits 
the type of subject you are trying to 
record.
 Flash CS
This mode will record consecutive images while firing the flash. See page 56 for 
details.
 Normal Speed CS/High Speed CS (Prerecord CS)
With Normal Speed CS, the number of  consecutive images you can shoot is 
theoretically unlimited, as long as there is  memory available to store them. Also 
note that the maximum shooting speed of Normal Speed CS is limited by the 
type of memory card you are using and the camera setup. See page 57 for 
details.
With High Speed CS, the camera conti nues to shoot images as long as you 
keep the shutter button depressed, and you can change the shooting speed 
while recording is in progress. You can  record up to 30 images. In this mode, 
half-pressing the shutter button starts continual pre-recording of images to a 
temporary buffer. Then when you press the shutter button the rest of the way 
down, the camera saves the buffer contents and perform real-time continuous 
shutter recording of new images until you release the shutter button. See page 
58 for details. • Note that even if the mode dial is set to  Õ (High Speed CS), High Speed CS 
image recording is not possible while  “Normal Speed CS” is selected for the 
“CS” setting (pages 57, 58).
 Single Shot
Continuous shutter recording is disabl ed when this mode is selected. Each 
press of the shutter button records  a single image. See page 26 for details.

IMPORTANT!
• When you use a BEST SHOT scene, the camera’s mode changes in accordance 
with specific setup (Single Shot, Conti nuous Shutter, High Speed Movie, etc.) for 
that scene. The recording mode selected by the mode dial is ignored.
• Due to the characteristics of the imagi ng 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.
• When recording with some modes, light s ource flicker can cause horizontal bands 
to appear in the image.
 HS
This mode records high speed movies. See page 68 for details.
 HD/STD
This more records HD or standard movies. See page 67 for details.

.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 pi xels 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 183.
• For information about movie image size, see page 65.
• For information about resizing  existing snapshots, see page 121.
.To select the image size
1.In the REC mode, press [ 8].
2.Use [ 8] and [ 2] to select the second control panel option from the top 
(Image Size).
3.Use [4] and [ 6] to select an image size and then press [SET].
Large Number 
of Pixels More detail, but takes up more memory. Best 
when you plan to print large-size prints (such 
as A3 size).
Small Number 
of Pixels
Less detail, but takes up less memory. Best 
when you want to send images by e-mail, etc.

RAW+ RAW+JPEG
(Select when

data yourself.) Saves the image as both normal JPEG data and 
RAW image data. A 10M size image 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.
