I have only used my triggers with my 580EX II twice now. And that was with cars. Booked a shoot on the beach with this nice family. I was really nervous about getting the shots right, but I think I calmed myself down and was able to get so OK results.
Equipment used:
Canon 5D II
Canon 85mm F/1.8 USM
Bare 580EX II with Cowboy studio triggers
