Yes
Where can can I pick one up and will one controll multiple flashes? I need to control the sb-900s without firing the on camera flash.
 
Sounds like a job for a Yongnuo RF-602. Transmitter on the camera and one receiver for each flash. £30 on Amazon or ebay for transmitter/receiver set.

Unless you want to retain ttl control, in which case you'd need an SU800/another SB900/800 or a tenner's worth of SG3-IR
 
Hmm well I used to have three sb-900s but sold one and didn't like the fact that you had to pop a flash on camera to fire the others.
Does the yongnuo allow me to use repeated flash too?

Ah yes. I took trigger to mean radio, for some reason.

Graham, are you still selling these things? You list of stuff is, erm, depleted of late.

What's the problem Adam? D700 will control remote flashes, and you can turn off the main flash from the pop-up if you don't want that. Or put an IR filter over it. Or use an SU-800 IR controller?

What do you mean by repeated flash?
 
Confused by the silly names lol, which one do you guys recommend?
 
Excuse me O.O
Please tell me to to turn it off lol, I figured it was the same as d90 (also which I couldn't turn off!)

I should read the manual, is this new to the d700?
 
Oh and repeated flash as in flashing in continuous mode without letting go of the the shutter release
 
I think we should start again.

What do you want to do? What have you got already? What is your budget?

Edit: by repeated flash, do you mean strobo mode?

Well studio shots is one and when I want a black background, flash from the camera makes it a pain in the ass.
Also want to do some sequence sports shots so I'll need my camera in CH or CL, and the flash set to repeat, but in the sb-900 manual it says you need an sb-900 on camera to use repeated and optional other wireless flashes.

I could probably spend up to £100 on them. I've heard alot about pocket wizards but seem a bit expensive.
On camera flash looks aweful anyway.

It sounds to me like you could use the pop-up on the D700 as commander unit, with the main flash function disabled. See handbook.

I'm still guessing at what you really mean by repeated flash, but if it's not stroboscopic then if the flash (SB900) is at low power should keep up with the camera for a short burst.
 
On the sb-900 it's called RPT, basically multiple flashes (repeat mode)
 
I've been told that its a PRE-flash thats firing off my camera to correctly expose the photo. So its not actually doing anything to the photo... But doesn't help the fact I cant use repeated/continuous flash without a commander on the hotshoe :(
 
Sequence shots. Need to have flash because I'm usually in dark places and the flash really makes the subject pop (hopefully a skateboarder once I get round to it)

Theres only 2 ways round this I can see.
1. Use one SB-900 on camera as a commander (it will still flash :() and the second SB-900 fireing wirelessly. The problem with only having one flash on the subject is that as soon at he/she goes out of the flash, it looks silly and uneven exposure throughout the sequence.

2. Buy a commander to fit in the hotshoe and control both speedlights wirelessly ad hopefully it will let me do repeated flash.
But I have like £50 in the bank so need recommendations for a good cheap commander/trigger or whatever will allow me to fire repeated flash.

Thats an example of a sequence shot, incase you didn't know already :)

not seeing the issue with using the built in flash, set to commander mode, with no output here. It'll meet your needs and won't cost anything.

Sure it preflashes and you get some visible light, but unless you're very close to your subjects it won't affect the exposure in any way. If it does then put either the Nikon widget they make for this on it, or find an old 35mm negative and tape it on

Having just done some quick experiments with a D700 and SB900

The only way to remotely trigger an SB 900 in repeating mode is with either

another SB900 on camera
an SB800 on camera
an SU800 on camera

You can't use the onboard flash to trigger repeat firing
You can't use a radio trigger to trigger repeat firing

So, buy another SB900/800 or an SU800 (p94 of the manual btw)

Or get / make a really long TTL cable, that'll probably work. Only just though of it, so not tested yet.

Agree with Hugh.

When you disable the main flash from the commander (it does actually still fire, but at extremely low/invisible power) it will fire a pre-flash, as it has to, but this doesn't appear in the picture - it happens before the shutter even opens. Maybe that's confusing things.

The example picture linked to above is a sequence of individial images blended in post processing. The only possible problem I can see with that, though unlikely, is that the pop-up commander won't be able to keep up with the camera firing at 5fps.* But even then, an SB900 will, so use your second SB900 as the commander unit.

No additional equipment required.

* Edit: crossed post with Jason. Maybe not then... ;)

Double edit: on reading post 24, well maybe yes after all :lol:

Forgot to mention in my post(s) above that you can set the D700 built in flash to Repeat, but this isn't an option in commander mode.

So, maybe, just maybe, you could achieve the result by having the SB900 in SU4 mode, and using the SG3-IR to block the flash. Unfortunately this is one I can't test as I don't have the filter.

Me, I'd go for either the long cable or the SU800. The SB900 can't be set to repeat when in Master, so it would be adding to the exposure and be no better than using the built in flash in this case.

Soooo

Time to shop.
 
one thing guys, the OP's description of repeating flash in post #9 is not the same as my understanding of repeating flash mode on these.

I think the OP's need to is for a fast repeat firing flash, with quick recycling in time with the shutter firing, holding the shuttter down, on 'continuous high' mode leading to multiple photos

but I understand repeat mode flash as strobing the flash while you hold the shutter open on a long exposure.

Big difference

That's how I read it Hugh :)

Provided the flash power is lowish, ie at close range/low f-number/high ISO then I don't see why it won't keep up with the camera on continuous firing for a burst of at least eight or ten frames. My Canon 580EX will do that no probs and the SB900 is a similar spec gun.

The pic the OP linked was not one frame with multiple flashes, but multiple individual frames merged in post.

But the OP specifies repeat mode here....


I agree, shooting in continuous and merging in post is the way forward, and then he's only limited by recycle time.

But.... more experiments ensue and I find...

You can't use the D700 onboard flash in commander mode when shooting continuous. I've tried it and it forces single shot, whether C-mode is set at TTL or Manual.

Switching to radio triggers (skyports in my case) and I can machine gun 8fps (I'm gripped with the badass battery fitted) with an SB900 set at 1/8 power for 20ish frames with nothing dropped (I'm shooting 16bit RAW and start buffering at this point the flash is still raring to go).

If I up it to 1/4 power then I only get 6 frames.

Same results with TTL cable as with Skyports, and I'd expect PW's and 602's should deliver the same. Since I can make this work with the TTL cable, and the SB on the hotshoe, I'll assume it will work on the SU800 too and the builtin flash is the limiting factor.

So....

1/8 power on the SB900 and it can keep up at 8fps (not fresh batteries either)

The buffer becomes an issue at this speed, use a fast card or shoot jpg if you're shooting for more than a second or two.

The onboard flash, in commander mode is not an option.
 
Just for completeness I've just tried shooting with the SB set to TTL and using a cable.

It doesn't work, it fires on the first frame, then every so often when it can catch up, so it's manual all the way for this type of shot.

I know most of us would already know this, but it was tested just to be certain...

I know you're absolutely right about what he is saying, and how it will work.

But the OP has something of a record and his description doesn't really match what repeat mode does

Ok so because of my so called "record" you assume I don't know what I'm doing even though you clearly havn't the slightest what RPT mode is, yet your still posting and havn't helped in any minute possible way. If anything, you've tried to send me in the wrong direction.

Jason, thanks for your in-depth reply and I guess I'll go and buy another SB-800 or 900 (The SU-800 costs about the same as an SB-800)
Annoying really because I just sold an SB-900 to get a new lens lol (But dammit it was worth it!)
Sorry about your card, batteries and actuations lol :)

Thanks again Jason!

please explain how rpt mode works then, cause from your posts it sounds like you were missing some fairly basic stuff
 
Nothing wrong with what I put.
The words repeated flash or continuous flash are fairly self explanatory.

if you say so, that'd be another fail then :shake: especially as you can't actually explain what rpt flash is :shrug:

Just to clear it up for you, rpt flash lets you strobe the flash over one long exposure, not multiple exposures as you were suggesting (holding the shutter down in ch or cl mode)

there's a big difference - you understand?

LOL have you actually any experience using the RPT mode on any SB-XXX series?

This is getting stupid now.

Once again you've shown a total lack of knowledge. You've asked a question and think you know the answer because that's what you want the flashes to do.

Some people who actually know what they're talking about set you straight, and your response is that of a 5 year old. Rather than thanking them for yet again taking the time to help you out you actually have a go at them because they've told you the truth.

Grow up would you, and start learning. You need to. Badly.
 
How long did I say Adam was going to last here again? Whatever it is, halve it. I was being very naive :lol:
 
I am sure we can tame him. Even if we have to crack the whips out.
 
Once again mixing your own words with mine, I know how it works. The question was already answered by Jason and you rant on.

Why is cross dresser talking now?
