New Canon Speedlites and ST-E3!

[Marsu42]

Presumably Canon is being conservative, and it doesn't work with all prior camera bodies, but I haven't heard of any tests with anything other than a 5DMKII.

Thanks - one more reason for me to save the money and get "just" a 5d2 now. Btw: the article says it works even on the 60d just fine: http://pixsylated.com/blog/canon-600ex-rt-first-impressions/

I have two 600ex-rts on order; when will the ST-E3-RT be available?  No one seems to have the ST-E3-RT.

I have it and been using it for a while, what would you like to know? Shot the attached picture with it and two 600EX-RTs outside in the rain.

I've had it for a few weeks now, and it works quite well.

Surprisingly enough the ST E3 and the 600EX RT also work with both the T3i & the recently announced T4i ,also the 600's do have AF assist beams and they will exchange data back and forth with the body, and Canon Technical support Has told me told me that there is away of running IR/Radio at the same time because i specifically talked about running my MT 24 EX optically and then without time to de rig shooting optically with my 600 EX RT's.

Unfortunately, there definitely is _no_way_ to use the 600rt optical and radio remote _at_the_same_time_, I guess it would be possible technically, but the flash firmware simply isn't build this way. I guess Canon wants to sell new rt units and maybe the upcoming rt receivers by blocking a mixed legacy path.

But you can simply cycle through the various master/slave/hotshoe modes with the new remote button on the left side, so maybe that's what Canon told you about quickly switching modes.

Btw, the other way around is also possible - you can set a cf to disable all rt or ir functionality if you only have the respective remote equipment to avoid confusion.

Mixed mode would have one drawback: you need time to account for all the preflashing going on.
Getting rid of the morse from the controller allows for those two additional groups, combining both modes would likely come with a mess of use cases not unlike the compatibility charts for F-mount.
Now putting the ST-E3 on top of a TTl-passthrough trigger not only gives the legacy flashes something to do but also doubles as the missing individual/manual group.

Well you can use RF and optical only flashes simultaneously, Syl Arena spelled this out on his CPM article. What you do is put the flashes in manual mode to disable any ETTL pre flash, then use a dumb optical slave trigger on your older slaves.

ST-E3 now works on the PW TT1 passthough

[victorwol]

So you are usingn TTL on some old models with PW and also the new Canon radios too? All at once?

I finally purchased a pair of 600EX-RT & one ST-E3 RT.

Moved from Phottix Odin, I must say that I'm somewhat a bit disappointed.

1. Lack of 2nd curtain sync.
My Phottix Odin can do this on any EX series flash. Why the hell ST-E3 RT can't even do this?

2. Lack of slave zoom control from ST-E3 RT.
Again, it is a feature that Phottix Odin can do.

3. Lack of USB port for potential firmware upgrade.
Look at Phottix Odin, they have numbers of improvements from their firmware upgrades.

Seriously if Canon can somehow implement a firmware upgrade on the ST-E3 RT & 600EX-RT to add those 2 above features (2nd curtain sync & slave zoom control), I'll gladly ditch my Phottix Odin completely & go for Canon.

Though, I'm glad I still have my Phottix Odin system. In the mean time, I'll continue keep using my Phottix Odin with 600EX-RT.

You can 2nd curtain synch all your flashes using a Synch cord and moving off camera. I agree though.. no wireless 2nd curtain is a pain.

Wow, I have never found a use for multiple second curtain sync, but I will give that a try.

Read it in a book you recommended to me=).

Haha, touché. Page 276! But I misunderstood you, I thought it meant you could use multiple flashes in second curtain sync, only the cabled flash can and any others have to be triggered via optical, the Odin offers full multi flash radio second curtain sync. Though I have still never found a use for it personally.

Very glad you got the book and obviously read it

Yup! It sucks you can do it wireless but I should have been a bit more clear.

[meenanm]

read through the thread and searched other sites. Is there a way to use the ST-E3 and trigger the flash with the Sekonic L-478-DR?

[scott]

Yes I've read that multiple places. Only with a 2012 camera I believe (5DMKII and 1DX). A ST-E3-RT will also remote trigger.

so does it work for the 6D

[Click]

Yes.

EOS-1D X, EOS 5D Mark III, EOS 650D, EOS 6D and the new EOS M mirrorless camera.
