Pressing the Shutter Button Formatting or erasing data on a memory card merely changes the file management information on the card and does not ensure its contents are completely erased. Be careful when transferring or disposing of a memory card. When disposing of a memory card, take precautions such as physically destroying the card to prevent personal information leaks. • The total capacity of the memory card displayed in the formatting screen may be less than indicated on the memory card. • Perform a low-level format (p. 159) of the memory card when the camera does not operate properly, the recording/reading speed of a memory card has dropped, when continuous shooting speed slows down, or when movie recording stops suddenly.

If you shoot without pressing the shutter button halfway, the image may not be in focus. 24
