....I am using my Canon 10d.
Just for fun I figured to pack one of my Vivitar 283's
as a back up to my dedicated Canon flash.
I am NOT mounting the 283 on the hot shoe.
When ever I take a shot with the 10d/283 combo
I get the shot and then I get the dreaded Error 99
code in the display and I have to take the battery
out to reset the camera.
.....
Well, exactly HOW do you (or rather, the camera) trigger the 283?
Any direct electrical connection between the camera and the flash can
put the camera at risk, even the PC outlet. Slave triggering is
safe, of course.
There is a useful web site with lists of trigger voltages for
different units:

where you can see that some 283´s spell instant deaths to most modern
digital cameras when connected directly.... (up to 600 V). I wouldn
´t risk it.
Of course, the voltage can also be measured directly with a modern
digital multimeter (if you know what you´re doing...); anything far
above 10 V is unsafe for many cameras, including Canons.
So, either get a slave trigger, or better, a modern, dedicated flash
for your camera!
