580ex not flashing at all

After have used it very strongly (many flashes at 1/1 power) the strobe doesn't work anymore. Everything seems to be OK looking all over the LCD, but the strobe doesn't charge anymore, it is not even audible the normal noise it makes when the capacitor charges any further. the "ready light" never turns on at all...

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If you are using the outdated wireless IR ETTL with a 580EX II as a Master.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

580ex won't communicate with Canon 7D (Because I dropped it)

Not sure about the repair costs but why not invest in a Phottix Odin wireless system? I use them in my work and they perform flawlessly. Small and lightweight plus they are wireless which means that the camera can communicate through windows and walls etc.
Hope this helps

580ex off camera shuts down after a minute or so of standby

No and no, the flash is by default programed to shut off after 1 minute .If you were using the flash on-camera, the flash would automatically power itself on when camera activity is detected but when the flash is detached, it doesn't wake back up.
To change this you have to turn off the auto shut off in the flash menu:
1. Power the flash on
2. Hold down the back light /C.Fn button until "Fn 00 0" appears on the screen
3. Rotate the selector wheel until you see "Fn 01 0"
4. Press your selector button down so that the 0 begins flashing
5. Rotate your selector wheel to change the 0 to a 1
6. Rotate the selector to the "Fn 14 0" position and set it to 1

7. Press your selector button to save this parameter
8. Press your Mode button to return to the main screen

Now your flash stays on as long as the flash switch is turned on ON, and as long as you have juice in the batteries.

Do not forget to turn off the flash after you are done.You can reverse it anytime, but you have to read the manual for that..

Same setup can be found in the manual

My 580EX seems to have low power

Hi Doug,

Try putting in 4 brand new batteries Lithium Energizer.
Or feed the Turbo Battery into the 3 pins port.

You flash is over 5 years old.
Or your NiMh are no longer holding a charge.
Do you have a DVM?

Flash quit flashing

To test the flash to fire without the camera:

Cut a wire about 4" long.
Strip both ends to about 1/4" to exposed the wire.
Turn on flash, wait until fully charged.
Touch one end of wire(lead) to Center of flash contact and hold in place.
Touch other end(lead) to side of flash.
This should fire the flash, if the tube or the cap is good.

Hope they are helpful.

Not working with my Rebel XTI

ALL Canon digital EOS cameras will work with E-TTL only. Solution: you need EX flash for full auto.
