Hey does anyone know if, when using a 580exII on camera in hss and remotely firing a second 580 will it wk in hss. Thus skippong the need for pocketwizards or the like?
yes it does
it uses IR so needs line of sight
you have to configure each flash first
the one on camera set to master
and the remote one set to slave
make sure they are using the same channel
You're going to have very little power with shorter speeds than sync. I use 2 x 580 at half and max power always when outside on sunny days. They're reversemounted in a 60x90 cm softbox..
