The flash output is adjustable from 1/1 full power to 1/128th power
in 1/3rd stop increments. To obtain a correct flash exposure, use a
hand-held flash meter to determine the required flash output.

Flash Output Range
The following table makes it easier to see how the stop changes in
terms of f/stop when you increase or decrease the flash output. For
example, when you decrease the flash output to 1/2, 1/2-0.3, or 1/2-
0.7, and then increase the flash output to more than 1/2, 1/2+0.3,
1/2+0.7, and 1/1 will be displayed.
Optical S1 Secondary Unit Setting
In M manual flash mode, press <
S1/S2
> button so that this flash can
function as an optic S1 secondary flash with optic sensor. With this
function, the flash will fire synchronously when the main flash fires,
the same effect as that by the use of radio triggers. This helps create
multiple lighting effects.
Optical S2 Secondary Unit Setting
Press <
S1/S2
> button so that this flash can also function as an optic
S2 secondary flash with optic sensor in M manual flash mode. This
is useful when cameras have pre-flash function. With this function,
the flash will ignore a single “preflash” from the main flash and will
only fire in response to the second, actual flash from the main unit.

S1 and S2 optical triggering is only available in M manual
flash mode.

Multi: Stroboscopic Flash
With stroboscopic flash, a rapid series of flashes is fired. It can be
used to capture a multiple images of a moving subject in a single
photograph.
You can set the firing frequency (number of flashes per sec.
expressed as Hz), the number of flashes, and the flash output.

a desired flash output.
Calculating the Shutter Speed
During stroboscopic flash, the shutter remains open until the firing
stops. Use the formula below to calculate the shutter speed and set
it with the camera.
For example, if the number of flashes is 10 and the firing frequency is
5 Hz, the shutter speed should be at least 2 seconds.
Number of Flashes / Flash Frequency = Shutter Speed

●
With high-speed sync, the faster the shutter speed, the
shorter the effective flash range.
●
Multi flash mode cannot be set in high-speed sync mode.
●
Over-temperature protection may be activated after 15
consecutive high-speed sync flashes.
Second-Curtain Sync
With a slow shutter speed, you can create a light train following the
subject. The flash fires right before the shutter closes.
●
Set Sony camera to Rear mode.
High-Speed Sync
High Speed Sync (HSS flash) enables the flash to synchronize with
all camera shutter speeds. This is convenient when you want to use
aperture priority for fill-flash portraits.
Press the <SYNC> button to turn on high-speed sync flash and
< >
is displayed. Then, adjust the SONY camera's shutter to
achieve high-speed sync flash (The High-Speed Sync function of
the earlier camera flash is directly controlled by camera).
