Old flash for off-camera use with D300s

[Dave in Wales]

I have an old flash, I do mean old, a Sunpak 24SR, which has a sync cord.

Can I use it off-camera and plug it into the D300s sync terminal, I don't want to damage the camera's circuits.

It will depend on the power output of the flash and whether it's safe to use with digital cameras. Some are, some arn't. If it isn't it could easily fry the d300.

Thanks for that, I'll use a slave unit instead.

Yes, I would use ebay triggers!

As already said, it's the voltages. I think the D300 is built for around 5 volts, the old Sunpaks (and others Vivitar etc.) if I remember rightly varied from about 5v upwards, approx 6-7v, 50, some even around 240 I think. I would say almost definately no and I'm not even sure if triggers are built for that. I had one of those little conical photocell flash slave thingys years ago..
