Review on High-performance Canon 550 EX Flash: Compatible with G6, G5, G3, G2, G1, Pro1, Pro90 & all EOS SLR Cameras by Robert Oner

I got this flash because my Canon 580 exii didn't work well with my Pocket Wizards (flexTT5) and I heard that this old flash had less interference. This works great, I'm going to marry this flash to my pocket magician and hopefully get a second one for my other pocket magician set.
