HOLDING THE CAMERA
To avoid camera shake, which can cause blurring of your photograph, hold
the camera steady.
● Firmly grasp the camera’s grip with your right hand.
● Hold the camera steady with your left hand and support the bottom of the
camera and the lens.
● Place your eye as close to the viewfinder as possible.
● Keep your elbow close to your body and take a half step forward for a more
stable stance.
SHUTTER BUTTON
The shutter button of the SD15 cameras
has two positions. When you press the
shutter button “halfway down”, the
camera’s autofocus and Exposure
Systems activate. When you press the
button “all-the-way down”, and the shutter will release to take a picture.
TIP
• Before you start to take pictures, we recommend that you operate the
camera, to become familiar with the “halfway down” position and other
features of the camera.

release the shutter. However, this can be changed from [Release Without
Card] on the Camera Set-up menu (P. 2 8 ).
