Canon - Speedlite 580EX II TTL Flash Reviews

I have a few of the 580EX IIs, and I love them. They're very powerful, provide great results, and are very well-built. The only thing I don't like is the lack of master/slave switch - the couple of seconds it takes to put it in master/slave mode can cost you a few great shots, and under pressure it can be hard to switch it into those modes. Otherwise, love it.

This is a wonder full flash. It does everything that I ask of it. The only problem is I don't have more of them :-) Since it does act as a master for the syncing, it would be nice.

My the only con that I have of it, is that it doesn't take a Li-Ion battery. It instead eats AA's for snacks.
