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?

SOURCE: How to restore factory settings

To reset the C.Fn settings on the flash just go into C.Fn mode and set each setting to 0.
If there is no C.Fn icon showing, the flash is at it's factory default setting.
Hope this helps :)

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If you are using the outdated wireless IR ETTL with a 580EX II as a Master.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.

I have been using my Canon 580ex ii with my Canon 5d mark ii. It will not fire at all now. I also tried my old 420 ex speedlite and it will not fire either. But, they both work on my Canon 40d.


You can actually set the external flash not to fire in the menu settings of your camera. Check there or try mounting the flash on your camera, turn both on and reset your camera to factory default settings through your camera menu settings.

580EX speedlite not firing


Does the pilot lamp light up? If so can you fire it manually by pressing on it? If the batteries are low it may simply just be taking a while to charge, the camera will not wait for it to be ready to fire and it may seem to be not working. If your flash can be fired manually however, there may be a problem with the cameras shutter or the hotshoe. You can do a basic check by pressing the star button at the rear of the camera, you should get a pre-flash. If not, there is a problem with the cameras hotshoe which you will need addressed by a service centre. If you get a preflash you can next check the cameras shutter by setting the second curtain to sync with the flash. This can be done via the cameras "Custom Function" menu, c-Fn 15. Set the camera to TV mode and chose a 1 second exposure. Take a shot with the flash attached, if the shutter is working correctly, the flash should fire a pre-flash and then a main flash. If it doesnt, the switch inside the shutter is broken and the shutter needs to be replaced. This is a pretty labour intensive repair and you may consider an upgrade as more economical.

I just got the 580 and had trouble with it blinking all the time, the bounce card was out about a mm and I did not realize it, once that was pushed all the way back--voila.
