Hi,

Just got an SB-900 to go with my D300s, I was wondering if its possible to use repeating flash mode, stroboscopic, when the flash is in remote mode triggered using the cameras onboard flash, CLS, or do I need an SU-800 or another SB-900 to perform this action?
I also have an SB-600 but this doesn't have repeating flashmode so I guess even if I make the SB-900 the master and the SB-600 a remotre slave this still is not possible.

Help please :)


Many thanks
 
You can't get CLS with repeating flash mode - it's effectively manual I think.
 
It would probably be kind of tricky using the popup flash as a trigger because the SB-900 would have to be in SU-4 mode as a "Remote" to see the on-camera flash as a trigger, and you only get "Auto" and manual power settings when in SU-4 mode.

But there's several ways you could get around it (not with CLS though).

1) Put an SB-900 on-camera in Repeat mode and use other flashes in optical slave mode (mileage may vary).

2) Put an SB-900 on a TTL cable from your hotshoe and have it in whatever position within the limits of the cable.

3) Use RF-602 radio trigger set.

I've tried all three methods, as it was something I wanted to try, and all three work to varying degrees.

What I ended up testing was the RF-602 trigger on the D300s hot-shoe, the RF-602 receiver on an SB-900 in repeat mode, then two more SB-900s and two YN460-ii flashes all setup as optical slaves (SU-4 mode on the other two SB-900s).

The SB-900s worked fine as optical slaves up to about 50Hz, but the YN460-ii flashes were intermittent much beyond 10hz.
 
How about setting SB 900 to MASTER mode and in the menu setting repeat to on?

I know it was possible to have SB800 as a RPT master and it seemed like an option on the sb900 i got today (but cant be bothered to try repeat master out yet!)
 
Tried it. Works perfectly. SB 900 to master. Option 2 - RPT - to ON.
 
Interesting, hadn't looked at that before.

I'm assuming it sets all flashes to use the same power setting you've set on the main/commander flash as all the slaves would be in their standard CLS slave mode?

Is the SB-600 capable of keeping up?
 
Guess it depends what power the 600 is set at. Tried it for 24x1/128th power flashes at 10 hz and it works fine. Don't suspect the SB600 is lacking that much power in honesty.
 
Where or what is option 2?
I can't find it in any of the menus on my 900 - and I can't find the instruction book either! I need to find my instruction manual, I even had trouble finding out how to get the menu up again to change the flash coverage setting.....must be getting old.:help:

Anyone any idea where I put that book of instructions?:bang:

Click to expand...

Set your 900 as master press OK for a few seconds till the menu comes up and turn RPT on.
Thats what I did and it worked
 
Bumping an old post, but with an update. After reading that it'd work with CLS I thought I'd give it a go. I didn't doubt that it would work, it just hadn't occured to me to try it until then.

Anyway, somebody on another forum last night seemed to suggest that the SB-600 doesn't work as a repeat flash no way no how. So, I had to prove my case. Thought some of you might be interested in seeing my little demonstration here.
