Flash sigma and St-e2

Rafael Motta · Nov 21, 2005

I have a ef-500 dg super from sigma. It works with wirelles TTL but i´d like to know if i can control it with the ST-E2 or with 550ex as a master???

Thanks

No, it doesn't work.

Sigma has not the same kind ow wireless controls. Buy another Sigma flash OR the st-e2 and a Canon flash.

Thanks a lot.
I have to decide what to do... I already own a sigma flash.

my ST-E2 will fire my sigma ST500 Super DG when you set it to the wireless mode

But can you use full e-ttl wireless or do you have to set the strength of the Sigma flash manually?

You're wrong. I have a Sigma EF-500 DG and it can be triggered by the ST-E2 as well as trigger another E-TTL when mounted on the camera.

It is fully E-TTL in wireless mode.

OK, sorry, I was slightly misinformed. I do however know a person ho has had some trouble with st-e2 and sigma!
But some research shows that most people succed with this combination!

Will (for example) the 20d built in flash trigger the Sigma flash when the sigma is used as a remote ?

I have a Minolta D7 Digital Camera and the (same type of) Sigma flash for the Minolta and it's built in flash will trip the Sigma flash when used as a remote flash.

I would like to get another Sigma flash (for the 20d) when I order the 20d (and new lens) --- but need to know how it works.

You can use the built-in flash to trigger a Sigma as remote if...

you use the Sigma as a manual slave (non-ETTL) and

set the Sigma power to 1/2 or less (it will recover after the pre-flash and fire as normal when the main flash is fired)

But you can't use the built-in flash to trigger any E-TTL slave in E-TTL mode.

It works on my st-e2 and 2 of sigma 500 super. I didn't have time to play around to master this combo. So far so good I can tell.

See some test drive with XT and kit lens, one sigma flash on the white paper background and one on the left with homemade sofebox, st-e2 on XT.

Have fun.

Thanks for your reply. I have not ordered the 20d (yet) along with a flash.

Based on your reply, I assume that it is not possible to override (eliminate) the Pre-Flash on the 20d built in flash. Is this correct.

The Pre-Flash would not be practical for my "normal" usage. I had hoped the camera would focus using the "focus assist" and that the pre-flash could be eliminated. I may be expecting too much. Although, I don't mind the "manual settings" part of using such flash since I have used many types during my many years of film camera usage for various cameras from 35mm to 4 x 5....

Forgot one thing.

Is there some place that I may download a Manual or Users Guide for the Sigma flash for Canon Digital camera usage.

there is a pdf-user manual somewhere on the net. I don't remember where I got it but I've sent you an e-mail with the manual attached.

I don't know about the 20D but on my 300D you can't disable the pre-flash. It's an integral part of the ETTL system.

The workaround is to tap the FEL button which fires the pre-flash manually, wait for the Sigma to recharge then take your picture.

Thanks for the information and for sending the Manual.

I just completed printing the English section and will review. I am anxious to see how much different it is when using with a 20d than my Minolta D7 with the Sigma Minolta version of the flash.
Thanks again....

it's the same.

or mount a cheap non-ettl, Auto flash wich has no preflash. but it's harder to control it..

Can i use the 550ex on camera and Sigma wireless with ttl working???

BlackSMP · Nov 22, 2005

I've tried and controlled a friends 420EX with my Sigma and I once tried anothers friends 580EX together with my Sigma but I don't remember if I used the Sigma as slave or master.

However, there are some glitches with Sigmas E-TLL control which sometimes made the 420EX fire with full power despite E-TTL.
