The Vivitar flash is 12 years old. It is a Nikon-dedicated unit. Is it okay to try this thing on my new N80? The N80 manual cautions against using third-party flashes due to incompatibility issues. I know some of this is just salesmanship but since the flash is so old, I thought I should ask. Obviously, I'm not much of an expert on flashes so any help would be appreciated.
I'm using a Nikon flash that old and it works fine. However, I know there is an issue concerning voltage (or something like that, I'm no flash expert either) that can be too high with older flashes and damage to the body can occur. Is this flash TTL?
Too be sure just measure with a voltmeter from the center pin to the side contacts in the mounting slot (ground). Iwould seriously doubt there would be a problem since any flash of sufficient technology to be a 'dedicated' unit is well after the industry switched to low voltage triggers. The usual culprits are the 283's since they were the flash used for the 'Last Supper' painting...
Make sure you measure the voltage across the center pin with the side contacts. I have several 283's the older ones measured 260v! the new ones made in Korea measure 6v dc. 260v will toast the electronics of your F80. So be careful with 3rd party flashes.

I have a Vivitar Auto Thyristor 550FD (with settings for ISO and modes - TTL, A1, A2 and M). I used my volt meter to measure the voltage between the center pin and the four other pins. First I took a 1.2 volt AA battery to make sure I was reading the meter correctly. It registered 1.2 volts. Then I checked the pins. The readings I got were .2, 1.2, 2.6, and 3.2. So it looks like these are in the safe range... correct?
