j Using the Self-timer
With <q>, the interval between the multiple shots may be prolonged
depending on the shooting functions settings such as the image-
recording quality or flash.
When you use a Creative Filter and shoot, even if you set he drive mode
to <q> (Self-timer: Continuous), single shooting will take effect.
After taking self-timer shots, playing back the image (p.98) to check
focus and exposure is recommended.
When using the self-timer to shoot only yourself, use focus lock (p.71) on
an object at about the same distance as where you will stand.
