Vivitar: In a nutshell, Vivitar was the house brand of a company called Ponder and Best, importers of a wide variety of photographic equipment. They sold quality lenses, flashes, and enlargers to the American photographer at reasonable prices. The Vivitar 283 was introduced in 1970 and was an enormously successful flash. It was followed by an improved version, the 285. Both versions were versatile and rugged, and far ahead of the competition.
Times change, and what was state of the art in 1970 has become quaint by the current digital standard. Still, these flashes can be used as optically triggered remotes. This is called the SU-4 mode in Nikon-ese, which means the flash will respond to a burst of light generated by another flash or infra-red trigger. All you would need is a Wein Peanut Slave and you would be in business.
Myth And Fact: Are Any Vivitar 283-285 Flashes Safe? The answer is a qualified "yes". First off, some facts: Nikon DSLRs appear to have more robust internal circuitry than the Canon, which has a voltage ceiling of 6 volts. The manual for the D750 clearly states:
"...Use only Nikon flash units.Negative voltages or voltages over 250 V applied to the accessory shoe could not only prevent normal operation, but damage the sync circuitry of the camera or flash.Before using a Nikon flash unit not listed in this section, contact a Nikon-authorized service representative for more information..."
If you can find a Vivitar flash with a triggering voltage of less than 249 volts, it is theoretically safe to use, but who knows for how long. But triggering voltages vary, depending on the country of manufacture. Let's examine the three Vivitar models and their variants:
283: The original flash. 4-stop automation plus a single, full power manual output level. They were manufactured in three countries:
- Japan: 280 plus volts in all samples tested. Late production Japanese units are said to have triggering voltages around 9 volts. One such 283 was offered for sale on eBay, accompanied by a photo showing it attached to a volt meter displaying a value of 9.04 volts. I considered buying it, but the bidding price was getting a bit out of hand. See above.
- Korea: Below 9 volts in all samples tested.
- China: Below 9 volts in all samples tested.
- Japan: Slightly below 300 volts in all samples tested
- Korea and China: No samples tested. I do not know if 285s made outside of Japan actually exist. I recently contacted 5 eBay sellers of 285s and asked the country of manufacture. All responded "Japan".
- Japan: Below 9 volts in all samples tested.
- Korea: Below 9 volts in all samples tested.
- China: 8.2 volts in the sample tested.
So are they safe? If you're using a Nikon DSLR and you flash tested out at the 9 volt level, you should be fine, but you do so at your own risk. I personally use my "safe" Vivitars only on my second-line cameras, such as my Nikon D70s, which incidentally allow me to use this flash at almost any shutter speed.

The Return of the 285HV: In 2007, the Vivitar 285 HV re-appeared, brand new, and for about $80.00. At first, everybody (including me) thought that we would be able to get a brand new, digital-safe reincarnation of this old workhorse. Unfortunately, it was all a dream, and Mr. Hobby, who initially announced its reintroduction, re-wrote his post to state that the new iteration was not worth owning.

Old Or New? I measured the triggering voltage on my new purchase, and it measured 4.22 volts. This puts it comfortably below the 6 volt maximum ascribed to Canon cameras. After comparing it with my older Ponder and Best era 285 HVs, I believe you can separate the new, less reliable units from the older ones by looking for the following:
- Country of Origin Cartouche: The earlier, more reliable units have the country of manufacture stamped just in front of the flash foot. Original Ponder and Best units will be stamped "Made In China". The new units do not have this cartouche, or any other origin markings.
- Pleather Texture: The plastic artificial leather trim on the zoom head will look like individual prick marks. Original units appear to have the texture of course sandpaper.
- Flash Head Hubcaps: The pivot points of the flash head are covered with a thin aluminum disk. Older models have a concentric circle pattern while the newer ones do not. Newer ones may still have a blue protective film covering these disks.

These units would have been worth the $80.00 price tag if the were reliable, but you have enough information to identify the sturdier Ponder and Best variations, should you wish to add a vintage flash to your gadget bag. Remember that the triggering voltages are NOT safe for the Canon bodies. It is not known if other digital bodies have the 6.0 volt limitations.

Many contend that the original plastic foot was designed to break before the accessory shoe on the camera could be damaged. It this was the case, adding this "built like a tank" foot defeats this fail-safe design. It does have a 1/4 x 20 thread at the bottom to facilitate mounting on a lightstand, but no locking foot for accessory or hot shoe mounting..

The Vivitar 285 HV is a viable, manual flash that is safe to use with some cameras. They can be used as off-camera remotes by adding a photo sensitive trigger like the Wein Peanut. If you can find one at a good price, it would certainly worth owning.
