Flash Mode - Manual Flash
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 Power 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: 1/2, 1/2-0.3, or 1/2-
0.7, or increase the flash output:1/2, 1/2+0.3, 1/2+0.7, 1/1.

Optical O1 Secondary Unit Setting
In M manual flash mode, press <O1/O2> button so that this flash can
function as an optical O1 secondary flash using its optical sensor. With
this function, the flash will fire synchronously when a second main flash
fires. This is the same effect as usng a radio trigger to fire the flash off
camera. This helps create multiple lighting effects.
Optical O2 Secondary Unit Setting
In M manual flash mode, press <O1/O2> button so that this flash can
function as an optical O2 secondary flash using its optical sensor. With
this function, the flash will fire synchronously when a second main flash
fires as in O1 but it will ignore the metering pre-flash and fire only in
response to the exposure flash from the main unit.
• O1 and O2 optic triggering is only available in M manual flash mode.
