Press < > button to enter C.FN-SLAVE to choose S2 function, 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.
Optical S1 Secondary Unit Setting
In M manual flash mode, press < > button to enter C.FN-SLAVE to choose S1 function, 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
● S1 and S2 optical triggering is only available in M manual flash mode.
This flash has three flash modes: TTL, Manual (M), and Multi (Stroboscopic). In TTL mode, the
camera and the flash will work together to calculate the correct exposure for the subject and the
background.
* Press <MODE> Mode Selection Button and three flash modes will display on the LCD panel one
by one with each pressing.
TTL Mode
Press <MODE > Mode Selection Button to enter TTL mode. The LCD panel will display <TTL>.
High-Speed Sync
High Speed Sync (FP 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.
