Re: flash stopped workin as master in wireless mode?

I have had this happen to my 580EX flashes many times. From what I understand, the internal circuit board can get overheated and burned fi you fire to many flashes in a row without letting the flash cool. Canon says not to fire more than 20 times in succession. Then you have to wait 10 minutes before firing the flash again!

Each time, I have sent the flashes into Canon for repair. I think they have a flat rate of $150.

Re: flash stopped workin as master in wireless mode?

I had similar problems - actuall was on one occasion settings - make sure switches are correct,,,one time it was the sslave flash being worn out - whole flash head had to be replaced as it was outputting 2.5 stops+ less light than specs and not proper calibrated at last repair.

these flashes i foind are reliable as slave master as long as you are strict about distances and positioning until either
batteries are dying
positiong not allowing communccation
flash head needs repair

of course settings correct.

I usually take a test shot of the slave flash firing before i start any lengthy or important shoots of poses or scenes

Are you using radio triggers for the wireless bit? The 580EXII doesn't work with Master Salve when using radio triggers.

Hi Joelgue,

Now, go to a real camera store and bring your equipments with you.

Say to them:

I have a Canon 580EX Flash and wanted to know if you have the Quantum Turbo Battery with the Adapter Cord for my 580EX?

Ask to see if you can test them out.

This adapter does not go into the 4AA battery hold but to the flip out cover, AC Adapter. You need to plug it into the flash.

Press "On" from the Q battery, then set flash to "Master" on camera and other EX to "Slave".

Turn all three on(1st flash, 2nd flash and camera.

Do not press shutter button but press the pre-flash(pre-auto lock/flash) on camera body. On the EOS-1Ds Mark III has "*".

Both flashes should come on.

Now, press the camera shutter using "ETTL Modes" and look at the image from the LCD exposure correct?

Address to this address from now, please:

PS: You did set both flashes into same channel and with no exposure adjustment, right?

The flash ratio between a master unit mounted on my Canon 5D Mark II and slave doesn't work properly. A couple of shots are fine but then all of sudden the slave unit fires ar full power, then a few week...

If you had the ATG Gold MG8k Flash Kim X3, then your 430EX II or 580EX II can transforms into wireless radio ATG ETTL II.

If you are using the outdated wireless IR ETTL with a 580EX II as a Master. Then you have to set the Slave (ATG/580EX II/430EX II) body facing close to the Master.

Canon Speedlite 580ex ii - won't work with camera

Caroline, you should try to set the camera on "M" and the flash in 2nd curtain flash sync.

Or set flash in ATG wireless IR ETTL Slave modes and pop-up the flash on Canon EOS-70D.

My flash fires before the shutter opens when in ETTL mode.

Are you sure those are not pre-flashes being sent out?
What mode are you in, Master, if so it is sending pre-flash to other flash.

Reverting to ttl - master flash not firing

Hi Kate,

What camera that you are having problem with those flashes?
Will switching the two have the same problems.
Make sure it is fully pushed forward into hotshoe & locked:-)

Try shooting second current, this will save you the repair costs.

Your exposure compensation was set to zero, but was your flash compensation set at zero?

Iam having a problem getting the two flash units to sink. I have set the parameters by the book for the master and the second the slave. They are both on the same channel. They are both on the ETTL mode....

Make sure the slave is far enough in fornt of the master flash to see it. If the two flashes are next to each other then the slave is not seeing the master signals.

Recently my canon speedlight 580 EX II TTL has been acting up...especially in low light situations. About on in 30 shots actually has enough light in them...the rest of the time the shots are...

that the camera/flash set-up I use ... there are many variables - iso/metering setting/shutter settings/flash settings .
If it's a flash function problem, try this to isolate it - first, with the diffuser/reflectors tucked into the flash head, and the head straight up, with the flash set in master mode, turn it on and look on the back screen. push the mode button til you see the ETTL in the upper left of the screen .. then press the set button in the center of the dial and the nuber in the center of the display should flash (+0) while the light is flashing, rotate the dial to change the setting (i usually under power by 1/3 stop. Play with the exposures a few times to get the feel for what the EV shifts do to your exposure. generally speaking, for interior low-light, i prefer to bounce off the ceiling (if low ceilinged), if there's too much direct it will give you an uneven and predominantly underexposed image.
if you prees the mode button you will come to the same options for adjusting the output in manual mode, but it will not work with the autoexposure in the camera.
Try playing with the ETTL settings
I think the problem may be that you have somehow altered the power output setting on the 580.
