Vivitar 283 or 285 flash and trigger voltage

    My question is can a Vivitalr 283 or a Vivitar 285 flash be used on a new
    digital SLR? I read somewhere that the 283 has a trigger voltage of 300
    volts and cannot be used on the digital SLRs but the 285 has a trigger
    voltage of 8 volts and can be used on the new digital SLRs.

    Can either be used on new or old (30 years old) film SLR? I currently own a
    Nikon Nikkormat EL that is 30 years old. Again, I am wondering if the
    trigger voltage, whatever that is, makes a difference.

    I measured my 283 yesterday at ~230V. It worked fine with my Canon AE1, but
    after reading recent horror stories about high strobe voltages and digital
    cameras I'm reluctant to risk it on my Nikon Coolpix 5700 unless I can fit
    an attenuator or interface unit !

    lacks. The trigger voltage is 2 - 300 V, and is not a good idea for a modern

    The Nikkormat was made when all flashes had similar voltages - shouldn't be
    a problem.

    Vivitar with Nikon D80

    I've just bought a Nikon D80 and tried it out with my Vivitar 283 which is about 3 years old. The camera was set in Manual mode and it worked fine; at 3 frames a second, the flash kept up with it.

    :eek: Then I learned about this "Trigger Voltage" Well you can imagine my horror at what might have happened. The camera still works fine, thankfully.

    :confused: Anyway, does the fact that I have used the Vivitar flashgun on the camera, without the camera exploding, mean that it has a safe trigger voltage?

    How do you measure trigger voltage?
