• This flash unit is set to high speed sync automatically when the shutter speed is
set faster than the sync speed. The sync speed differs depending on the camera
used. For further details of the sync speed, refer to the operating instructions of
your camera.
• If you press HSS button again, high-speed sync is cancelled. When high-speed
sync is cancelled, the shutter speed cannot be set faster than the sync speed.
• Taking photos in bright locations is recommended.
• High-speed sync cannot be used with bounce flash.
• When using a flash meter or color meter, high-speed sync cannot be used
because it interferes with the proper exposure.
Flash Sync Speed
Flash photography is generally associated with a maximum shutter speed
referred to as the flash sync speed. This restriction does not apply to cameras
designed for high-speed sync (HSS) photography (page 34), since they allow
flash photography at the maximum shutter speed of the camera.
