I just bought a cheap EOS RT from ebay to do some comparison tests between film and digital.

I remember that when my dad had an EOS 620 it used an EZ flash.

As the EOS RT is about the same vintage as the 620 I'm wondering will the 580EX work on it or is it not backward compatible.

Thanks

Answered my own question. RT arrived today and it does work with the 580ex albeit not in E-TTL mode
