slow shutter speed (p.58) that reduces camera shake. The slowest
shutter speed depends on the focal length of the lens in use.

Using Slow-Speed-Sync

You can use slow-speed-sync in . (Night Scene Portrait) or b (Shutter
Priority) mode when shooting portraits with the sunset in the background.
Both the portrait and the background are captured beautifully.
• Slow-speed-sync slows the shutter speed. Use the Shake Reduction function
or turn off the Shake Reduction function and use a tripod to avoid camera
shake. The picture will also blur if the subject moves.
• Slow-speed-sync shooting can also be performed with an external flash.
