• High-speed sync is cleared when the high-speed-sync button is

pressed again, and a shutter speed faster than the sync speed can no

longer be set.

• It is recommended that photos be taken in bright locations.

• The flash range with high-speed sync is less than for normal flash

photography. Check that the subject is within the flash range before

taking the photo.

It is possible to figure out the accurate flash range with high-speed

sync by using the table of HSS flat flash (ISO100) on the page 46.

Divide the guide number by the aperture. This is the maximum dis-

tance of the flash range.

For example, when applying the shutter speed of 1/500, with a 28mm

focal length, the guide number is 8 according to the table. Devide 8

(the guide number) by 4 (the aperture), which equals 2. The flash

range would be 2 m in this case.

The number will be doubled, when using ISO400 film.

• High-speed sync cannot be used with ratio flash, or bounce flash.

• When using a flash meter or color meter, high-speed sync cannot be

used because it interferes with the proper exposure.

• High-speed sync lamp of the flash might be lit even with a camera

which dose not have high-speed sync. In that case, high-speed sync

dose not work.

• With a DiMAGE digital camera, the flash will sync with all shutter

speeds regardless of the HSS setting.

HIGH-SPEED SYNC [HSS]

High-speed sync Normal flash

Press the high-speed-sync but-

ton.

• The high-speed-sync lamp glows on

the control panel.

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 4, 3, STsi, QTsi, 400si, 300si and Dynax 4, 3, 3L, 500si,

500siSuper, 404si, 303si, 300si do not support this function, and high-

speed sync therefore cannot be used.
