Vivitar 285hv

I own a Vivitar 285hv and a istD. The flash works great on the hot shoes. Since the istD does not have a pc sync connection how can I use the flash on a bracket attached to the camera ? I have seen various hot shoe connectors advertised. Which ones would work and can I use the pc cable that was supplied with the flash with them?
Thanks for any suggestions... Charles1

You just need a hotshoe adapter that has a female PC socket on it. And then yes, you can use the 285's sync cable.

To connect to the cameras flash termal, you need an adapter with a normal cotact on the bottom of the shoe, not a 1/4-20 socket.

Thanks Dave, what about using the Sonia wireless remote ? Have you tried that product ?

Charles,
No, I haven't. I just use a Nikon hotshoe adapter to allow the use of the 285 on a bracket. This is necessary when using the flash for verticl shots. I plan on doing some more experimenting in the future.

How you researched the possibility if the flash damaging the camera with a high sync voltage?

The Vivitar 285hv is low voltage (designed for newer digital cameras)

Charles, The Vivitar 285's have been around for quit a while. One was reported to read 350 volts on the flash trigger voltage site. I would check any used units with a meter, before using. Better safe then sorry.

It's true, the 285HV has been reissued with a lower trigger voltage, it's unclear how many of the older ones (like mine) are in a safer range. If you didn't buy it new, (and maybe even if you did) ....*test.*

AFAIK, there's no way to tell just by looking, which you have.

Some, as I recall, had a grey back panel rather than a black one, ...not sure what that may signify.

Non-HV 285s, and, unfortunately, 283s, are right out. Those can trigger more like that 200 or 300 volts, cause they didn't need to isolate the flash circuit from the trigger.

Lady,
Some newer 283 and older 285's like mine have low voltage. My non-HV 285 has 7.5 volts and my old 283 has 250 volts. I always test first.
