5.2 Automatic flash sync speed control
Depending on the camera model and the selected mode, the camera’s shutter speed automatically changes to flash sync speed when flash readiness is reached (see operating instructions for the given camera).
Shutter speeds faster than the flash sync speed cannot be set or will automatically be changed to flash sync speed. Various cameras feature a sync speed range, e.g. 1/30th sec. to 1/125th sec. (see the camera’s operating instructions). The actual sync speed used by the camera depends on the camera mode, the prevailing ambient light and the focal length of the lens.
Shutter speeds that are slower than the flash sync speed can be used, depending on the operating mode selected on the camera.
