    I currently own a Sunpak MZ440AF-PT that I use with my Pentax film camera's. Am I able to use this on my canon 20 D also. I did try it and cannot get the camera to fire the flash. The flash fires manually. Is this just a complete mismatch or I am doing something wrong. I am on the manual setting on the canon and the flash.

    thanks in advance!!

    I couldn't find that flash on THIS SITE, which shows 'user reported' flash trigger voltages.

    The list was meant for older Canon cameras which had a rating of 6 volts or 9volts. The 20D has a safe rating of 250 volts (As far as I know).

    It's posible that the flash requires too much voltage and might damage the camera, but I'd guess that it's unlikely. I don't know why it wouldn't fire, is it a standard size hotshoe and does it fit well on the canon?

    An alternative would be to get an off-camera radio flash trigger set.
