Can the Canon speedlite 430EX be the slave to the 550EX speedlite

Sunds like it's broken

Bruce,
Try these steps:
1. Set camera to manual2. Set shutter to 1/60
3. Set aperture to F5.6
4. ASA/ISO 200
5. 550EX on hotshoe
6. Do not set on slave or master
7. Turn on flash


Display must shows, ETTL.
If that doesn't work, you have to use the flash on manual.
Some of this model will not work fully on ATG Canon EOS-1D C, ATG Canon EOS-1D X IR, Canon EOS-1D X/60D/T4i because this flash is over 20 years old.


Unless you would want it to be modified by me.
But that can be costly when you can get the 580EX II for less than $425.00 USD.

Yeah you should go into the menu on your camera and see if there is anything you need to change!!

1. Make sure the trigger you are using is compatible with digital flashes.
2. isolate the smaller contact so they do not "short out" on the trigger.
3. make sure the trigger is working and will fire other flashes

Good luck

From what I've experienced the slave need to be set to B-1. Don't know why.

I'm guessing you're talking about a wireless connection...

Unfortunately, the 430EX can only act as a slave. You'll need one of the following to act as a master control unit: 550EX, 580EX, 508EX II or the ST-E2 transmitter :-(

if u set the 580ex on master and the 430 EX on slave it works :) u dont need STE2 for this simple task.
