Question about Canon Speedlite 580EX II TTL Flash

Open Question

Canon 580ex ii won't turn on. I think I plugged the battery grip into it upside down. Heard a short buzz sound then nothing. Tried fresh batteries and nothing, but batteries do get very hot.

Yes. If you were able to set a faster shutter speed, then you would not expose the entire frame and would have the shadow of either the first or second shutter curtain (or both) partially masking the frame.

At higher speeds, the shutter is never fully exposed: before the first shutter curtain has finished travelling across the frame, the second one has stated it's journey. All SLR's have this issue and on some older models you could only use a maximum 1/60th of a second.

In practice though, in dark conditions the "slow" shutter speed does not affect exposure as the true exposure will be determined by how much light the flash puts out, and it puts this light out in as little as 50 microseconds (50 millionths of a second) for a modern electronic flash bulb.

Faster shutter speeds can be used successfully, but only with flashes which operate in high speed mode. What they do is to make the flash burst seem longer by rapidly firing the flash bulb many times. This trick can ensure that there is sufficient light to expose the frame at the highest shutter speeds. Shutters which operate at, say, 1/4000 may seem fast, but compared to the speed at which a single electronic flash burst operates, it's an eternity.

Most likely that Capacitor has "Gassed" as we say. It is now destroyed, however usually too the Driver Semiconductors "Blow" as well. I have seen this before, it is not uncommon. An enormous amount of energy is stored in this capacitor and circuit, and they often fail in an explosive manner.
What you need to do, is find a Canon authorised servicing center, contact your local or head office of Canon, and inquire as to a local repair center.
Now when you take the Flash in for repair, please ask for a 'Quote" before allowing any repair work to commence, this then will allow you to make an informed decision as to repair or replace.
It is hard to give an exact cost but I would expect, that around $80.00 to $125.00 for the basic repair, would be about right for a repair. BUT depending on what exactly was wrong, it could very quickly escalate.

I think you may find, that the cost of repair, may even approach, the cost of a new unit? This is also why getting a "Quote" is beneficial.

However if you can desolder and solder, could obtain the EXACT Rating and Value Capacitor and Semiconductors, (read ALL damaged bits) and were prepared to do a little work, it is entirely possible to repair this unit oneself. but be very careful when doing so, as flash guns can give a very very nasty "Bite" (speaking from experience :) lol)

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 :)

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.

I have a Canon battery grip for my Canon EOS 300D but have no manual to tell me how to use it as the camera is 2nd hand, can i get a manulal or download one from anywhere


I understand there isn't a manual, just a quick how-to guide. Here's some basic use info from a review
http://www.the-digital-picture.com/reviews/canon-bg-e6-battery-grip-review.aspx

The Canon BG-E6 Battery Grip is designed specifically for the Canon EOS 5D Mark II as shown above with a Canon EF 16-35mm f/2.8 L II USM Lens mounted. To get the Canon BG-E6 Battery Grip into the position shown, the LP-E6 Battery is removed from the 5D II and the battery door detaches. The BG-E6 slides up into the battery compartment and locks into place via the tripod socket screw seen on the BG-E6 just below the lens in the above image. The BG-E6 provides its own tripod adapter threads - this functionality is not lost.

The Canon BG-E6 Battery Grip holds two Canon LP-E6 Batteries that deliver double the number of shots or video time from the 5D II. Alternatively, use 6 AA batteries in the included Canon BGM-E6 Battery Magazine shown below.

It wont power up at all. I have tried batteries,


1 - Check the battery contact and make sure the batteries in the flash are good.
2 - check the plug for the turbo, make sure it is not damaged, as well as, the high voltage plug on the 580 flash. If those contacts look dirty or mushroom shaped, you will nee the flash repaired.
3 - obviously make sure the turbo is charged
