Hello again
I would like to thank everyone who replied to my problem.
Actually, I don't think I really had a problem, it was just that I didn't
how the flash worked. I took a picture in ETTL mode and I could see the
flash through the viewfinder. I then put the flash unit in MANUAL mode and
there was no flash visible when I took a picture. I'm sure that is the way
it should operate.
I would like to thank you all again.
Jim

You probably saw the preflash previously because you were using second
curtain sync and a slow-ish shutter speed. With normal 1st curtain or
high speed sync you can't usually distinguish the preflash from the main
flash, although you might occasionally see the preflash through the
viewfinder if the light is low enough.

If you press the 2nd button on the right of the 580EX you can cycle
through normal 1st curtain, 2nd curtain, and high speed sync modes to
get your visible preflash back with slow shutter speeds.

Hi Jim,
If you can see the 'flash' through the viewfinder when taking a shot
then the preflash is working - that is what you are seeing. This test
is best done in a darker area.
You cannot see the main flash through the viewfinder (with the viewing
eye) as the mirror is up.
Hope this helps

Cheers,
Allan
