High-speed sync (HSS)

High-speed sync

Normal flash

High-speed sync eliminates the restrictions of flash sync speed and enables the flash to be used through the entire shutter speed range of the camera. The increased selectable aperture range allows flash photography with a wide aperture, leaving the background out of focus and accentuating the front subject. Even when photographing at a wide f-stop in the A mode or M mode, when the background is very bright and the shot will normally be over-exposed, you can adjust the exposure by using the high-speed shutter.

Press the high-speed sync button (HSS).

• The high-speed-sync lamp comes on.
