Canon - Speedlite 580EX II TTL Flash Review

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.
