Canon 540EZ --- 550EX

[Guinness]

Hi folks,

I have an Canon 300D and use a Speedlite 540EZ. The problem is that I have to use the flash on manual setting. Have re-read the manual and it reads:
"When using an external Speedlite, use an EX-series Speedlite. The
flash cannot be fired with an EZ-, E-, EG-, ML-, or TL-series
Speedlite set in the TTL or A-TTL autoflash mode. Use the
Speedlite’s manual flash mode instead if provided."

This is a bit of a bugger (the 540EZ was bought about 3 years ago). Is there any way around this problem of not being able to use A-TTL or TTL short of using the manual option or purchasing another flash?

Thanks in advance.

Unfortunately, NO. The Canon digital cameras only operate in ETTL, manual or Auto if your flash has its own thyristor and Auto Mode. TTL and ATTL are not available. Your only option with an EZ flash is manual. Only EX series Canon flashes are ETTL. You can also get a 3rd party vendor flash that is dedicated to Canon ETTL.

As a result of this, there have been many -EZ flash units dumped on the used market. The -EX flashes do E-TTL as well as whatever the -EZ did.
