I should actually not have poked my nose into this at all, having neither a 430EX, an EOS 5D Mark II, nor an EOS 7D!

I have all three, but in fact, I probably should not have poked my nose in until I actually tried it out, as opposed to simply checking the manuals.  I'll find some time in the next day or two to give it a real-world test.

I know it sounds crazy, especially since it isn't an advertised feature, however when controlled by a 580 that is set on multiflash/stroboscopic, the 430 takes on the same characteristics... if you look at http://photonotes.org/articles/eos-flash/ and scroll down to the multi flash area, it shows the 420 and 430 as supported flashes.  I played with it just long enough to see that it worked, however I will play with it with my flash tonight.  I got my 7d at my office but no 430 with me at my office to test right now.  I will let you know either way tonight/tomorrow.   

Well, I see I may have been barking up the wrong tree. The manual for the 430EX flash unit makes no mention of its having a multi-flash mode.

So I guess now my question becomes, "using the 430EX with the EOS 7D, can a multi-flash mode be invoked (from the Camera)? On a 5DII?"

Again, the mention of that mode in the 7D manual does not mean that it is available on any flash unit (even all those that generally can be controlled from a modern EOS body). The manual cautions that the available modes vary with the flash unit.

I should actually not have poked my nose into this at all, having neither a 430EX, an EOS 5D Mark II, nor an EOS 7D!

Carry on.

Best regards,

Doug

if you look at http://photonotes.org/articles/eos-flash/ and scroll down to the multi flash area, it shows the 420 and 430 as supported flashes.
I don't find anything on the page that link goes to regarding the multi-burst (stroboscopic) mode.

There is some information about using the units in a multiple-unit situation.

What am I missing here?

Best regards,

Doug

If you scroll down on the links to part III there is a link for stroboscopic and setting stroboscopic flash.  As I said before I will test this again at home with my flashes.  I know 100% the oncamera flash does it and that the 430 is capable of it, however it could have been on the camera hot shoe and not wireless... let me play with it and I will let you know my results.

I have a 430 and a 580 and am glad to have both. The 430 is pretty full featured and a consistent shooter. Very good as a slave. It's also smaller and lighter so an easy flash to carry when you don't need to blast at full power--which is more times than you think. I'd say the main negative for me is not being able to use external power. Sometimes I need fast recycle for work. I need fast more often than that extra stop of light. So I just end up taking the 580 instead. It's nice to have the option of either or both.

Regarding the matter of multi-flash operation of the Speedlite 430EX, I posted an inquiry on another forum directed to the attention of Chuck Westfall of Canon USA, their Technical Advisor.

**********

From Doug

The Canon Speedlite 430EX is not shown by its manual as providing a multi-flash (so-called "stroboscopic") mode on a "local" basis. However, the manual (p. 27) indicates that this mode may in fact be utilized when using the flash unit as a slave in a Canon wireless flash network with all "Type A" bodies and most "Type B" ("TTL") bodies.

Is this in fact true?

From Chuck:

Yes. It requires a master unit that supports MULTI flash, such as the 580EX II, 580EX, 550EX, or the EOS 7D's built-in flash. (PS: The 60D and T3i built-in flash units can be used as master units, but they do not support MULTI flash.)

From Doug:

In another forum it was commented by one correspondent that the multi-flash ("stroboscopic") mode could be invoked (via the camera flash control menu) when the 430EX was used on an EOS 7D body, but not when used on an EOS 5D Mark II.

Is there in fact ever the opportunity to invoke multi-flash operation of the 430EX (other than perhaps as a slave unit in wireless flash network operation)? If so, in connection with which EOS bodies?

From Chuck:

The only way to achieve multi-flash operation with a 430EX or 430EX II is through use as a slave unit in a wireless flash configuration controlled by one of the eligible master units listed above.

Chuck Westfall of Canon USA has recently advised of a correction to his original summary of the circumstances in which the Speedlite 430EX (and 430EX II) flash units may operate in the multi-flash ("stroboscopic") mode.

He had originally said that the units could operate in that mode only when operating as a slave and the master is a Speedlite 550EX, 580EX, or 580EX II or the onboard flash unit of an EOS 7D.

He now advises that he has determined that in fact the multi-flash mode cannot be utilized by way of the onboard flash unit of an EOS 7D as a master. When that facility is set to the multi-flash mode, its operation as a master is disabled.

Thus, the Speedlite 430EX (or 430EX II) can only operate in the multi-flash mode when operating as a slave and the master is a Speedlite 550EX, 580EX, or 580EX II.

Again, to avert any misunderstanding, the 430EX (or 430EX II) apparently cannot provide the multi-flash mode when being directly operated from any camera, whether or not that camera provides for setting the associated flash.

Chuck's recent notice is here:

Just wanted to add a little of my own un-worthiness. I have a 430EX II that I use with my 7D. I love it. I really haven't tried the 580 so I can't say how much better that is, but 430 flimsy? I don't find anything flimsy about it. Could the one who stated that please elaborate?
My guess is that the 580 must be built like a tank to improve in build quality over the 430...  ;D
