Was given to me by a mat at an auction in Woodburn for helping him carry out his bought camera items.

"Caution with this flash"
The Vivitar 2800 is an older model with high voltage (200 volts) on the hot shoe. This was ok on old cameras with mechanical sync contacts, but can destroy the circuitry of modern digital cameras. Some cameras can handle it fine. Check the specs on your camera before mounting this in the hot shoe. Or use it with an off-camera slave trigger that is rated for 200+ volts. Or buy a Wein Safe-Sync (but it's hard to justify $47 for a safe-sync when the strobe only costs $15). I bought two of these strobes and I am working on an optically-isolated modification to make them safe for all cameras.

The strobe has a thyristor exposure control circuit with two ranges so that you don't have to keep changing your aperture manually when the subject distance changes. Just set the aperture according to the slide calculator on the back of the unit.

There is a popular movement for use of smaller hot shoe flashes off-camera. (See the Strobist blog by David Hobby http://strobist.blogspot.com). The Vivitar 2800 is a great little strobe for this kind of use.
