Question 1

how do i set up my canon 600 ex with my pocket wizard plus iii so i can start taking pics with my flash off camera ?

Accepted Answer

The Canon 600EX-RT speedlight is designed to work, wirelessly, with other 600EX-RT units (the "RT" stands for Radio Transmission), or with the Canon ST-E4; you no longer need 3rd party transceivers (such as the PW Plus III) to incorporate off-camera flash using radio transmission. Another company, YongNuo, has developed a shoe-mount transmitter (the YN-E3-RT) that is fully compatible with the 600EX-RT and also has an AF assist light, which the Canon ST-E4 doesn't even have. If you're still set on using your PW Plus III with your 600EX-RT, you can do so but you will only be able to use the flash in Manual Mode (not E-TTL), and you won't be able to change your flash settings remotely. This is fine if you're shooting in a controlled environment, such as a studio, where your lighting won't change but if you're looking to use off-camera flash outdoors and/or in changing lighting conditions, I'd highly recommend getting another 600EX-RT, which you can then use as a transceiver on-camera to fully control your off-camera one. If that's too expensive an option, get the Canon ST-E4 which also mounts onto your hot-shoe and gives you full control over your 600EX (or get the YongNuo version, which does the same thing but is a lot less expensive and also has the benefit of an AF assist beam for low-light focusing).

Question 2

can I use Canon 600EX-RT to control my 430EX II as a slave unit without a separate trigger?

Accepted Answer

Yes and no - Yes it works as traditional IR way, but that requires clear line of sight between two. You cannot use radio feature of 600ex-rt to trigger 430ex

Question 3

Can I use this flash with my Canon 5D (not a mark ii or iii)?

Accepted Answer

Aloha Andrew, Don't know to what extent you mean 'USE', but I tried it on my friends 5D mrk i and it works perfect in ETTL and manual, I also tried the ST-E3 on camera (5D mrk i) and fired the 600ex rt off camera and that worked too.  I think when Canon says it's built for the 1DX and 5D mrk iii, I believe they're talking about it's ability to work in conjunction with the camera's newer 61 point focusing systems.  Hope that helps!

Question 4

Will the Canon ST-E3-RT Speedlite Transmitter run at full 1/8000 of a second speed-sync with my Canon 60D?

Accepted Answer

It will work up to 1/8000 sec as long as you are in High-speed sync mode. Just remember that the flash will work at a much reduced power level in that mode.
