Second curtain flash with the st-e2

Hey guys
is it possible to achieve second curtain flash with the st-e2 a 1dmkiin and the 580ex ??

Cheers

No, it's not, unfortunately.

I've been sitting waiting for Canon to release an updated ST-E2.

Heck, all they have to do is take a 580EX ii and rip everything off from the swivel up and add a red cover and light...
(Probably close to what it would be. And would probably have an MSRP of $400 selling for $300. Of course I'm guessing as the 580EX ii has an MSRP of ~$500.)

I want something lighter than a 580EX/EX ii on top of my camera.
Since I use all my 580's inside, I'm not to worried about misfires.

If you're implying that an ST-E2 with the 580EX II's "mastering" capability will give you 2nd curtain sync, I'm afraid that won't be the case because even the 580EX II as a master doesn't provide 2nd curtain sync. But, just the same, I'm waiting for an ST-E2 II to come out, also (although I still haven't decided if I'd buy it or not if it were available).

Not implying that.

I just want an updated ST-E2 so I don't have this huge monster sitting atop my camera.

Every time a ST-E2 subject comes up, I have to put in my 2 cents...

I am very doubtful that Canon will ever release an updated ST-E2. A number of patents prevented Canon from integrating ST-E2 functionality in the camera (as Nikon does) and also prevented radio controlled E-TTL slaves (directly, not with the workaround implemented by radiopopper). These patents will expire in a few years, so any new/updated ST-E2 would be obsolete/redundant/use​less by then except for (then to be) old cameras ...

BTW: I have the impression that second curtain sync over wireless E-TTL doesn't work due to protocol restrictions, e.g. the fire pulse must come within a very short time frame after the remote flash settings commands are transmitted.

Does Quantum hold the patent for the RF ETTL slaves because they do have products that allows them to implement ETTL commands to the flash via RF?

Yes, that's the same impression I have, too.

I wouldn't think Canon would release a RF version of their system anyway. (Not in any immediate future andway.)
Too much would have to change and it people wouln't be happy if it wasn't backword compatible somehow.

However, I can't see why they couldn't update the ST-E2.

When and if the time comes that they decide to put in built commanders to units with built in flashes, they would be forced to upgrade the ST-E2 as well.

Am I not mistaken that Nikon's SU-800 can do quite a bit?

Just my 2 cents anyway.

Did I mention I wanted an upgrade to the ST-E2 yet?

I am not aware of any Quantum patents. I do know the pocketwizard patent (which covers triggering a flash via RF commands) and a Minolta patent (which covers remotely triggering a flash from a camera). Since it is possible to license patents, I assume Quantum did this (or avoided the patent somehow). Radiopopper avoided the patent since their product is not connected to a camera, they use the electro smog produced by the flash bulb to detect the flash commands (no idea how pocketwizard sees this, but it seems to hold so far).

@m3rdpwr: I tried to point out why Canon most likely won't update the ST-E2. All these "I want" yellers won't buy that new ST-E2 once their cameras can do the same and better. Nobody will want to continue with IR kludge once RF systems are available. Ideally Canon made wireless RF E-TTL to E-TTL hotshoe converters to accomodate their current flash lineup. But realistically, nobody knows what they are up to.

Understood, but if they do come out with a "wireless RF E-TTL to E-TTL hotshoe converters to accomodate their current flash lineup" you can be sure it will be expensive and have some stupid odd-ball battery in it...

Shame never mind ill grab a cable then for the odd times that i need it

btw what does the second curtain set up in the 1d menus do ??
Was flicking threw the custom settings and saw it havent had a chance to try it out

It does not do anything if you are using a flash that allows you to set the 2nd curtain sync feature on the flash itself. But if you have a flash like the 420EX which does not have that feature, the custom function will allow you to operate the flash in 2nd curtain sync mode.

if im using the st-e2 tecnicly it dosnt have the feature so would it class it in the same? just a thought

Nice try but no, it doesn't work that way.
