Shutter Button
To ensure your shots are in focus, always begin by holding the 
shutter button halfway down, and once the subject is in focus, 
press the button all the way down to shoot.
In this manual, shutter button operations are described as 
pressing the button halfway or all the way down.

Images may be out of focus if you shoot without initially 
pressing the shutter button halfway.
• 
Length of shutter sound playback varies depending on 
the time required for the shot. It may take longer in some 
shooting scenes, and images will be blurry if you move the 
camera (or the subject moves) before the shutter sound 
ends.
