Canon FD/Vivitar 283 compatability : LUSENET : Canon FD : One Thread

Folks: I got a lucky break not long ago, and picked up a Vivitar 283 flash for $3 at a flea market. I then found a PC cord for it, and it seems to work well on my original F-1 when triggered off the PC cord. I also checked the output voltage between the tip and shield of the PC cord when it's charged up, and it'a around a volt. I understand this to be low enough not to damage my AE1-P, which I'd also like to use it with. My question is this: there's a single metal contact on the shoe, which is otherwise all plastic. How does this flash work with a hot shoe like the ones on the A-series? All my circuits classes taught me that it takes two connections to make a circuit!

If you look closely at the foot you will also see a contact above the ankle, as it were. This touches the side of the hot shoe and completes the circuit.

Hi Michael, Duane is right about the second sync contact. It's in the slot between the shoe "sole" and the flash body. I thought I'd add that we've been using an old 283 (circa 1976) with our AE-1P since 1984 without problem.

Thanks, folks! I took a closer look and found what seems to be a spring contact in a slot just above the foot. I assume this to be my missing contact.

As a result of this closer inspection, I also found that the foot had cracked and been glued back together, something I understand is a common occurrence with 283's. Has anyone tried one of the aluminum aftermarket replacement feet?

Thanks again!
