Can you explain how this would be achieved? I got a 300EZ from eBay and stuck it on the 20D. I'm guessing that "A-TTL" is enough different from "E-TTL" that it can't do anything automatic (though it does seem to fire the IR light for focus assist, and zoom the head in sync)? I cannot currently get the 300EZ to fire in anything other than test mode. It seems like the flash is so simple that there shouldn't *be* that much I should need (or could, really) to do to make it work. I have tried it in P, Av, Tv, and M modes, and the only time it fires is if I hit the test button on the back. I want to find out who has actually used a 300EZ with the 20D or other digital body so that I can find out whether I got a bum flash, or if they just don't work together, as much of Canon's stuff seems to be fond of. > Regards, Stefan. -/\/ * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
