Question about Pentax AF-500 FTZ TTL Flash
The brands use the flash contacts to communicate to the camera. They do not make their flashes compatible with other brands. Don't mix brands. Even if trigger voltageis not an issue, the TTL and AF is not going to function.

SOURCE: Vivatar 283 and Nikon D70s
The Vivitar 283 was manufactured in China & Japan over a number of years & the specifications did change over this period.
The older Vivitar flashes had a voltage on the shoe which could reach 150 volts whilst the later ones had voltages of only 5 to 9 volts.
If you have, or can get hold of, a small voltmeter then you can measure this voltage.
Turn on your flash & let the unit charge up to 'ready' & connect the meter between the contact in the centre of the shoe & the little contact tucked away in the lip of the shoe. (DC volts not AC) There is no danger to you in doing this!
This should tell the voltage on the shoe of your unit & if it is 15 volts or less, it will be fine with your digital Nikon camera. If more than 15 volts than best not to use it.
Hope this is of some help!

r-sensor to plug in accessory remote sensor for use instead of the fixed one on the front. This allows flash to mount to the side with the remote sensor on the hotshoe. The other socket that has the interlock with the power switch is for a high voltage input (500V input!) from a special mains powered adapter for continuous power and faster refresh instead of using the batteries.

When using a digital camera with a flash unit of unknown trigger voltage, you are risking the life of your camera. Excessive trigger voltages can disable the cameras internal circuitry to the point where it is totally beyond repair.
I do not have, in my files. the trigger voltage for the specified flash unit. I only have the specs for larger portables and studio flash gear.
A simple test , however, will reveal the exact trigger voltage. If you have a multi-meter or a DV voltmeter with a 250 VDC range (just to be in the safe side) you can preform this test at home or an electronics service technician can do it for you in a few minutes.
The test lead are placed across the synch contacts on the foot of the unit or plugged into the sunch socket if the flash unit has one. If the reading is more that 4 or 5 volts you can still safely use the flash with the aid of a protector device which goes in between the flash and the camera. Theses are available at better camera shops and dealers.

the nikon D80 has a 250 volts safe range and i have the same issue but readin on the internet i learned that yo can now the voltage of your flash with a voltage metter ond the hot soe.
Vivitar 283 has diferent ranges of voltages depending on the year of fabrication so older ones can achieve 300 volts and earlier have 230 volts so the best is to get a vivitar 285hv for about 75dollars or a safe sync for about 55dollars, you can find all on ebay or other brouser the safe sync converts up to 400 volts to a safe 6 volts that are yust the normal voltage for digital flashes.

No. First the Canon 199 was designed for the Canon camera, and the electronics are very different in the Nikon. Two the 199 was designed for film and the digital metering is completely differnt for digital. Buy a Nikon flash.
