580EX with 430EXII

Hi,

Could someone tell me what is the wireless working distance between the 2 mater/slave flashes?

How well is this setup as 580EX on camera hotshoe indoor and outdoor?

Thanks.

Indoor you will do pretty well the distance is about 45ft except in large places like a gym then it completely unreliable and frustrating, out doors its about 30ish feet i think but its just like working in a gym and forget about it if your competing with the sun

If you can keep a direct line of sight in a place like a gym, I've found that it works pretty well. But since there are no nearby walls or ceiling to bounce from, it's inferior compared to inside a normal living room or similar.
