Repeating flash ■ Setting the flash output level, the number of repeating flashes, and the frequency (Hz) per frame • The number of flashes (Times) represents the number of times the flash fires per frame. • The frequency (Hz) represents the number of times the flash fires per second. • The number of flashes is the maximum flash firing number. Because the Speedlight fires during a single exposure, the actual number of repeating flashes per frame falls below the one set as the shutter speed increases or the number of flashes per second decreases. • Referring to the table below, set the flash output level, the frequency, and the number of repeating flashes separately for each picture.
