One thing I discovered when I was adding the flash to the reviews was that it also sends white balance info to the camera. That means color balance when using the flash should be better. Hopefully that means that 580EX flash photos won't be quite as cold as previous flash images. I think that's cool - errrrr - warm?
Considering the number of aritcles and selling points that 420 compatability would generate it is suprising that they left it out. I think i will call tommorow and see if i can find out...the local shop seems to have the knowledge.

I assume the white balance feature is an ETTL II feature? It is a logical thing to do since you know what proportion of exposure is coming from the flash with ETTL, just dont see how a non ETTL-II body could use that feature.

lol on the cold warm thing, lets just say phat to delve back a few years and make it even more ambiguous.... :-P
