Because the EF 500 DG Super flash is available for different camera protocols, I suspect the one with the "EO-ETTL" is for Canon cameras. I'm not too sure about the other one.
Make sure you get the correct version.

Just recieved sigma reply regarding the flash.Confirm that there are 2 version of sigma Ef 500 DG super for canon mount.
Old = sigma EF 500 DG super(canon mount)
new= sigma EF 500 DG super EO-ETTL(canon mount,with ETTL II capability.
think will drop the idea of buying the old version, where topping up $60 give u the new version.
