Hi James,
Yes, the 550EX uses the main flash tube to send the wireless E-TTL
control signals.
The only alternative is to use the ST-E2, which uses a filtered red
emitter, but with less range and angle of coverage.

Just bought a 2nd 550EX to use as a slave flash, using wireless E-TTL.
Followed instructions and tried to set the master flash (on camera) to
'OFF', but I noticed that when I fired the shutter both flashes pumped out
light. Yet when looking at the test shots on my D30, the main light seems to

Dark background is very important, or you can underexpose the background.
This is ( http://evrimgallery.com/Proofs/JacquelineM/jacq_2_023s.jpg ) one
that worked a little better than another one, in which it was very dim

Well, no. Each flash _group_ fires one after the other in the pre-flash
stage. When the picture is taken, then the flash groups fire
simultaneusly.

Thanks Gary,
There are lots of things indicating that the Sigma EF 500 Super
is a great slave flash for EOS cameras.

Umbrella in English terms, like hood is a bonnet (I think).

Yes, you can fire the EF 500 Super optically with any flash. But the manual says
not to use a flash in ETTL mode because it will set it off to soon.

I recently got a EF-500 Super and I asked Sigma if the multi flash ratio control
works with the Elan 7 and they said it works with the EOS 1v, EOS3 and Elan 7. I
also called Canon and they said the Elan 7 will support ratio control with the

Does Elan 7 allow ratio control? I love my Elan II but the lack of ratio
control limits my creativity in certain cases. Of course after getting a
flash meter etc it might not be necessary.

Ok, I don't own a second flash yet (I'm going to buy the Sigma EF 500 Super
as soon as funds allow), but I was wondering about how flash exposure
compensation works in a 2-flash situation. Here's the scenario: the EF 500
would be on the camera, and the 420EX would be on a stand or something, off
