Funphotons, are you saying that you can use the 600ex on camera like a st e3 rt unit to control other flashes?
Wow, thank you. I must rethink the ste3rt, because for around 300 I can get another flash that communicates. Hmmm...
Yes. I am reading the manual on the 600ex and I see that the master can be set not to flash while the slave flashes. However, having the master set to flash makes for a nifty bounce fill if needed. Thank you
At the bottom of page 55 in the manual it addresses this and when flash is set "on" it fires as slave group A, now I must figure out what means.
