I'm looking to upgrade my flash system and OCF triggering system. Currently, I have 3 x 580 EX II (which I love), and two different triggering systems: the ST-E2 transmitter (which has a built in focus-assist - AWESOME), as well as Elinchrom universal skyport transceiver system.
I like the ST-E2 and master/slave setup with the 580 EX IIs d/t the fact that it transmits ETTL-2 data to the OCF. However, I hate the fact that it is infrared, requires line of sight, and does a crappy job outdoors.
I like the elinchrom system because it is extremely reliable and triggers pretty much every time d/t the radio frequency transmission rather than IR. However, it's more "stuff" to deal with, and can only be used in manual flash mode.
I've been thinking about getting the Pocketwizard system (Flex/Mini), but after several hours of research, I'm seeing that the 580EX II needs to be modified to reduce RF interference, and that this particular PW system is unreliable with the 580 EX II. HOWEVER, I've also seen many articles stating that the PW are MUCH more reliable with the 430EX II system, which would be somewhat of a downgrade from the 580 EX II.
I've also been looking at the newer 600 RT system. Does anyone have experience with this new system of flashes? Reliable? Consistent? Worth selling all 3 of my 580 EX II for 2 x 600EX RTs? Would eventually like to have 4 flashes in total. I've also read that the new hotshoe trigger from canon (ST-E3-RT I think) does NOT have a focus assist beam built in, which is ridiculous in my opinion.
I've NO experience with the 600 RT system...
