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.

SOURCE: Broken flash Canon 580 EX.

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 :)

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.

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.

Canon 5D and canon 40D are they type A or type B cameras as per 380 EX manual

Hi Bruce,
You have the latest cameras and they will work with ETTL II with Canon 430EX/550EX/580EX and 580EX II. Earlier models use ETTL and films use TTL.
Hope they are helpful.
