Optical O1 Secondary Unit Setting
In M manual ash mode, press <O1/O2> button so that
this ash can function as an optical O1 secondary off
camera ash using its optical sensor. With this function,
the ash will re synchronously when a second main ash
res on the camera. This is the same effect as usng a
radio trigger to re the ash off camera. This helps create
multiple lighting effects.
Optical O2 Secondary Unit Setting
In M manual ash mode, press <O1/O2> button so that
this ash can function as an optical O2 secondary off
camera ash using its optical sensor. With this function,
the ash will re synchronously when a second main ash
res on the camera as in O1 but it will ignore the metering
pre-ash and re only in response to the exposure ash
from the main unit.
• O1 and O2 optic triggering is only available in M manual
ash mode when the Modus 600 RT is off camera
