Using the Slow-speed Sync Flash
Slow-speed Sync slows down the shutter speed. To avoid camera shake,
either set [Shake Reduction] to Q (On), or set it to R (Off) and use a tripod.
Note that the picture will also blur if the subject moves.
Slow-speed Sync can also be performed with an external flash.
