I've got one of these and I'm happy with it, but I've not tried any other ring flashes, so have nothing to compare it too. It takes 4 AA batteries, but 7dayshop 2700mAh batteries are a tight fit, so they don't spring back against the battery contacts, hence I can't use them in this flashgun.
how are these for beauty/portraits?
Hoppy, how do you find that RingFlash adapter for macro? That looks like a good alternative with a 580ex to an 580ex AND a dedicated macro flash ring.
Mmm, some investigating me thinks.
Sorry OP for the little hijack - Hope you don't mind.
