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 Function Button 3 < > 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 Function Button 3 < > 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 optic triggering and off camera high-speed
mode are only available in M manual flash mode.
