flash units for Canon 350Ds...

    Today's my day for asking blindingly obvious questions.

    I have a flash gun which I occasionally use for taking indoor photographs. For various reasons which I won't go into because I don't have a photograph to illustrate the point handy, I needed it for some outdoor photographs and realised a limitation of the flash that I do have rather quickly - it has a terribly long recovery time, ie you take picture, you want 30 seconds then you take next one. Yes, it's an older flash unit, but okay - to date, I haven't used it so much.

    I know a handful of you have newer flash units so what I want to know is this - before I go figuring out how to justify yet more money on that camera - do they recover fast enough to work with continuous shooting? It's specifically for continuous shooting that I need it - if it's not really possible, then I'll forget about it because for the amount of flash photography I do, it really would want to do exactly what I need it to do before I go spend more money on something when I already have a decent flash.

    (and no, it's not for the exposure problems I mentioned below)....

    I have a 430ex and it can recycle in about a second if you are using it outdoors and about 7 seconds max on full power. I think?

    This article talks about high speed synch. MIght be what you are looking for.

    You can get external power packs that will recycle much faster. The 580ex on my 20D is good for 5fps...but only the odd burst, you can't shoot continually.

    Roen, I'd say 5fps would do me. The Canon shoots off 3fps and I usually needed the second of the sequence...

    will look into it.

    Thanks a million both of you - I'll have a look at that link and see what I can learn.

    Edit: - that's a very useful link Borderfox - strangely enough there's something in there that I might be able to draw on for the other problem I posted earlier, the exposure/fill flash issue.

    ta very much.

    Just tried it on the 5D at 3fps and it works no probs. The second and third may be at a reduced output though. That's where your external power source will come in handy.

    Shove your ISO up to as high as you are comfortable with, and the flash will re-cycle quicker (as it's going to use less power on each shot).
