For details on the operation
When a long exposure of one second or longer takes place,
the noise reduction process is performed for the duration that
the shutter was open. While the noise reduction is being
performed, the message "Processing..." appears on the LCD
monitor. You cannot take the next picture until the process is
over.
This mode does not perform noise reduction. This is suitable
when timing of shooting takes precedence. However, this
makes the noise more conspicuous. It is recommended that
you activate the noise reduction if you use long exposure.
Automatically adjusts the focus.
• This mode uses up the battery charge faster than [Off].
