Depends what they mean by compatible. Sometimes that just means "won't blow up the camera" and "will fire under some circumstances".

Flashes similar to 420EX Speedlite?

Also wondering here, does the 420EX come with some sort of shoe plug and cable that allows you to have th flash off camera at all?
Seems like that would be useful if you can't afford the terribly high price of the wireless remote thingy that Canon sells.

It doesn't come with the flash, but you can buy the cable separately. I don't recall the price, but I don't think it's more than $50.

Are you talking about the 420ex?

No, he is talking about Sigma flash.

I'm sorry the reply took so long. My modem was struck by lightning
(.I checked ST's manual in slovenian translation and it doesn't say anything about that.
I also compared results from Auto and P modes and it's identical. I checked it only when flash was the only light source.
No. I'm talking about Sigma 500ST DG which is similar to 500Super. Differences are described below.
Yes, it's true. You can set exposure compensation through G3's menus and it works as it is supposed to. If you want to use manual mode you can set a number of different flash outputs between full flash and 1/16 of full output. You can also select 2nd curtain sync through menus.
Of course you can tilt and swivel flash's head. And it has a built-in diffusor for 17mm focal lenghts.
It's not Canon that improved E-TTL. It's Sigma that corrected it's support for it. Older Super and ST versions (non-DG which means digital) worked fine only with the EOS line but not with Gx line.
DG series improved flash electronics and it works fine.
Use filter adapter with the G3 and balance will be fine. I use it this way with my Sigma which is the same size and weight as 550EX and I don't have any problems.
I'll explain on Sigma's case.
The principle that Sigma uses is called "reverse engeneering".
What they do is they buy original Canon's flashes. Then they "tear" them apart to see how they work and with knowledge obtained through this process they design their own flashes which are not neccesseraly identical to Canon's.
My 500ST DG is not a copy of any Canon's flash while 500Super is a copy of 550EX. Mine has some features lacking.
But Canon doesn't favour this actions so they modify logical circuitry in cameras so they won't work with Sigma's flashes.
That holds true even for some lenses. Some older Sigma's AF lenses don't work with newer EOS cameras. What you have to do is send those lenses to Sigma to upgrade firmware.
Example: Mark B. pointed out that his 500Super unit doesn't work with a G1. This is due to the process described above. Neither would any other Sigma's unit without DG mark on it.
But Sigma replied to Canon's changes with DG line which stands for digital. This line of flashes works fine with EOS as well as Gx series.

Hellow Andrey -
I'm surprised they allowed you to use flash in the cathedral.
I wonder if you were pointing the flash straight ahead? Or whether bouncing it higher might have been used to good effect?
Additionally, I believe Metz makes a flash that is also said to be on the level of the 550EX, possibly even more useful and compatible than the EX flashes.

I was going to answer similarlly.
The point of the flash is to get the room lit. Not much else. Balance is secondary or even a tertiary condition.
I suppose you could also get a flash bracket so as to enable better gripping of the entire system.

I was wondering about the possibilities of having the flash to the side...how would you get the flash bracket assembly to work? Is there some kind of extention cable with a foot on one end and a foot receiver on the other with the same connection points as the canon foot on both?

The shots were made by my wife in Italy. And yes, they allow to make shots using flash. Sometimes you have to pay something for this.
Flash was pointing straight ahead.
As for bouncing flash higher - I am not sure, but I think you need a special reflector in this case.
I am not aware of this.

I have an English manual. It says in plain English: "Set the camera's mode to Full-AUTO Mode". Though Av and Tv mode are also mentioned.
I made some additional testing, and everything seems to be working fine - in all the modes. I think I understand what was the problem. I was making my tests at home, and made the shots at too close a distance with the lamps also working. This resulted in almost white pictures, which I thought to be the result of using incorrect mode. But now I repeated the tests trying to shoot at more then 2 m or in the darkness - and it works OK!
The flash seems to be too powerful for home shooting. graph (g3)

what is the difference between 420ex and the sigma sigma500st? which will be lighter?
Andrey Platonov
Well-known member
The weight difference is minimal: according to the specs, Sigma EF 500 DG ST is 320 g, while 420EX - 300 g (without batteries).
But Sigma is more powerful: its guide number at 105 mm is 50 m, while 420EX guide number at 105 mm is 42 m.
Otherwise they seem to be quite similar.

What about the head movemennt? Isn't it swivel/twist in Sigma vs only one direction in Canon?
