I am working on a solution to address this very problem for a D70. Be VERY careful about using unverified information on suitable non genuine flashguns.
There is a lot of info if you care to Google search for trigger voltages for flashguns. There is one list that has some highly doubtful info as the persons measuring the voltage used the wrong type of meter.

Ideally a cathode ray oscilloscope with a minimum 10 megohm input impedance should be used to look for high voltage spikes.
If a digital multimeter with a 10 meghom input impedance was used you may get fairly close to the true trigger voltage but the DMM will not reveal any spikes.

Analogue multimeters should never be used as their input is too low and they WILL load the circuit giving an incorrect low voltage reading where you think you will be safe when you are NOT.

Regards,
Doug.

I dont have any problem with Vivitar Flash.. I am currently a Nikon D3000 user and I need an external flash for shooting in low lights and portraits in my garrage-made studio..I searched ebay and found...


The Vivitar 285 HV is specified to have a trigger voltage of 12V. The Nikon DSLRs are specified to be safe up to 12V. This puts the combination right at the fuzzy point. It should be safe, but if the flash goes a little high while the camera goes a little low, you might run into trouble.

The 285 (no HV) is definitely a no-go.

What is the diff between a vivitar 285 and a vivitar 285hv?


285 has high trigger voltage(+250v) ,where as 285 HV has less than 5.5 volts trigger voltage (which is safe to be used for any digital SLR2_bing.gif). 285 HV has a Thyristor circuitory.

Can the Vivitar 283 be used safely on Nikon Digital SLR Cameras?


I assume you're asking about the 283, not the DF-283 which is compatible with digital cameras.

As for the 283, yes, if you put an adapter such as the Wein Safe-Sync between the camera and the flash. Under no circumstances should the flash be mounted directly on the camera.

Instructions on how to use the settings. Any manual available? Can I use it with my DSLR?


The 285 was a fine flash but is not compatible with the newer TTL and exposure system in the digital cameras. Buy a new flash like the Promaster 7500EDF this is the 285 of today.

Can i use vivitar 285 hv flash with my canon powershot sx10 ?


It is the HV version, yes you can just put it in a color mode so the sensor on the front guesses the out put- it isn't ttl so it won't know what the camera is thinking

Switch from film to digital cameras.


I also own a Vivitar 285 that i used with my Canon F1 manual 35mm camera. Most older cameras before the advent of digital, had a hot shoe on top of the camera, or like in my case, the hot shoe went over the rewind knob. I also had to plug in a power cord from the 285 flash foot and the cameras PC connection in order for the flash to work on some other cameras. The Canon Rebel XTi has a TTL (through the lens) hot shoe usable with Canon's own EX flash units. You can buy a "hot shoe to PC connector" if the TTL camera hot shoe doesn't work, but be extremely careful, the only problem that exists with the older manual flash units was the trigger voltage is as high as 200+volts which would fry digital camera hot shoes. I tried my unit with a Wein flash trigger device on the PC cord of the flash and my Canon D60 with it's own flash. All shots were overexposed and washed out highlights.  Here's a copy of the hot-shoe review:h The EOS 400D's hot-shoe can be used with Canon and third party flashes (although sync only on most third party units). The hot-shoe is E-TTL II compatible. Compatible flashes include Speedlite 220EX, 380EX, 420EX, 430EX, 550EX, 580EX, Macro-Ring Lite, MR-14EX, Macro Twin Lite MT-24EX and Speedlite Transmitter ST-E2.  The Canon Rebel XTi doesn't have a PC socket to plug in a manual flash trigger cord which common sense tells me there is no provision to step up the voltage to trigger manual flashes - so my answer is this combination is not a good idea on a Canon Rebel XTi. Hope this helps.
