The message began like this:
“Help! My Canon 540EZ flash doesn’t work on my new digital SLR.”

That’s right. To my great disappointment, I discovered that myself. Canon “EZ” series flash units that were made for film cameras don’t work at all or with very limited functions on the digital SLR bodies. You need one of the “EX” series flash units. Two good current models are the Canon 430EX and the Canon 580EX (see the links that follow).
