I'm new to this forum. Would like to know how to high sync Canon 80D + Canon 430ex II wireless ( like 1/2000 etc....)
Thanks in advance.
I don't believe it is possible. The slave unit (430) will do what it is told by the master (80D) and the 80D doesn't support HSS with its flash unit. You would need an ST-E2 unit.
Perhaps third party flash triggers. I don't know anything about them.
