HIGH-SPEED SYNC (HSS)
High-speed sync Normal flash
1. Press the mode button to dis-
play or on the data
panel.
2. Press the select button to blink
[HSS].
• The currently selected high-speed
sync setting ( / ) also blinks
simultaneously.
High-speed sync eliminates the restrictions of flash sync speed, and
allows you to use flash over the entire shutter speed range of the
camera. The selectable aperture range is increased, allowing portrait
shots with flash in which the aperture is opened to leave back-
grounds out of focus and thus accentuate the human subject.
• The Maxxum STsi, QTsi, 400si, 300si and Dynax 500si, 500siSuper,
404si, 303si, 300si do not support this function, and high-speed sync
therefore cannot be used.
3. Press the + or – button to
select .
4. Press the select button repeat-
edly until blinking stops.
• [HSS] remains on the data panel.
• High-speed sync is cleared when is selected with the procedure
described above, and a shutter speed faster than the sync speed can
no longer be set.
• It is recommended that photos be taken in bright locations. When pho-
tographing in dark areas the shutter speed will not exceed the sync
speed, even when is selected.
• The flash range with high-speed sync is less than for normal flash
photography. Check that the subject is within the displayed flash range
before taking the photo.
• High-speed sync cannot be used with multiple flash, ratio flash, or
bounce flash in the upwards, left, and right directions.
• When using a flash meter or color meter, high-speed sync cannot be
used because it interferes with the proper exposure. Either select
to clear it, or select a shutter speed less than the sync speed.
