Does anyone know how well the transmitter works outdoors? I was thinking about using one or two 580EX's outdoors with an umbrella/stand. Wondered if the IR can transmit with strong outdoor sunlight and/or if an umbrella would block the IR signal? I have had trouble with IR transmitters firing my monolights in larger buildings with cinder block walls.
Is there an option to use some type of pocket wizard to fire off multiple 580EXs, even if it meant using them in manual mode only? Might need an adapter or something, but I have not looked into it yet.
Also, excited to announce that the Canon 1D Mark III I ordered on June 8th is on it's way to me right now! Almost expecting the UPS guy to show up in a Santa suit tomorrow morning.
