FLASH – High-Speed Sync
Attach the 5400HS flash and set it to standard mode.
• The camera will automatically switch to HSS mode and H will appear in the
viewfinder and data panel.
• HSS cannot be used under fluorescent lights.
• Flash and color meters cannot meter the flash when high-speed sync is
selected.
The maximum sync speed for this
camera is 1/125. However, with the
5400HS accessory flash (sold
separately) shutter speeds up to
1/4000 can be used. High-speed
sync (HSS) allows faster shutter
speeds when fill flash is used on
moving subjects outdoors.
Refer to the 5400HS instruction manual for details.

HSS also lets you use large aperture/high
shutter-speed combinations to separate
your subject from the background by
limiting the depth-of-field.
