Is the yn568ex a way way better deal than a 580ex I or II?
Does it do everything the 580 ex II does?
Small issues with colour balance?
Lack of power port.
I have a 430ex ii and 580EX ii (use as master of short or possibly long cord) and am mulling over getting a (low cost?) 3rd flash for very amateur indoor work (most set-ups seem to need 3 light sources). I am thinking ETTL mainly. Possible experiments with HSS and rear-curtain etc.
I see there are similar threads I could have revived, but I think my query is slightly different to warrant a new topic.
