Another issue with third party flashes and triggers is that they often do not work with new Canon Models, and the wait for updated firmware can be 6 months if ever.  That's probably OK for a cheap flash, since it won't last long anyway, but for a expensive trigger system, it might make someone unhappy.

roadrunner,

Glad it all worked out for you.

As Neuro said you can use HSS, you do lose a fair bit of flash power however it allows sync at any speed, and after you go past about 1/400 you are down to the shutter duration limiting flash power via any strobe anyway. The first couple of stops do take a big hit though, moving from sync speed to one third higher costs about 2 stops of power, by the time you get to 1/1000 the Canon flashes in HSS are working more efficiently than relying on long duration flash . Also as Neuro says, remote triggering is very easy, I have the SR-N3 cable for my pre 2012 bodies. The only limitation I have found is you can't trigger remotes with an unattached ST-E3-RT, you can with a 600EX-RT. Page 68 of the 600EX-RT manual covers remote release from a slave operation.

Indeed this was one feature that appealed to me for my real estate work, I can set up my camera on a tripod with an ST-E3-RT on it and walk around with a 600EX-RT and point the flash where I want for accent lighting, push the button and the camera is triggered by the flash I am holding, that is then triggered by the camera! Very cool system.

With a 5DIII you can do high speed sync with the RT system (although not with pre-2012 bodies).

Just a clarification on that point as the manual is far from clear. HSS via RT does work on some/many/most (?) pre 2012 bodies, just not in combination with ETTL flash metering (warning at the bottom of page 25),but it might/should work in Manual flash mode. Also whilst many pre 2012 bodies do not support RT ETTL at all (page 51), and no pre 2012 bodies are supposed to support RT ETTL and HSS at the same time, my 1Ds MkIII's do and are 100% reliable in that mode.

Thanks - seems like Canon was either conservative in their specs, didn't bother testing, or <cynical>know full well these things work, but are underhandedly pushing people to buy new bodies for supposed full compatibility</cynical>.

I think, giving Canon the benefit of the doubt, they were cautious and they didn't bother testing the multitude of legacy products for exact specs. Of course this works both ways, it "encourages" people to buy newer bodies, but on the flip side more accurate info might have encouraged more 600 sales to older camera owners who don't intend upgrading bodies but do want better flashes.

For instance, the specs say my sync speed goes down one stop in RT mode. I have found this is not actually true most of the time, but is sometimes, that is, I sometimes get a shutter shadow  at 1/250 but most of the time don't. I haven't pinned down what, exactly, is the setup that does get the shadow but I well understand Canon just saying "you lose one stop of sync speed in RT mode" rather than going into every combination of every camera, can you imagine the outcry if they didn't put that proviso in there and people called them out on it?  :)

What I was hoping for prior to purchasing my RT system, was actual user feedback on their own real world results, I never could find it though which seemed strange bearing in mind all the people here who listed owning 1Ds MkIII's and 600EX-RT's, yet not one of them, even via PM, could give me any heads up at all.

Canon 600 EX-RT Cons:

I lost the ability to sync my flashes at 1/400 or 1/500 (Depending on the camera I was using) compared to that standard 5D3 sync speed of 1/200.

No ability to trigger a remote camera

With a 5DIII you can do high speed sync with the RT system (although not with pre-2012 bodies).

You can also fire the camera remotely with from a flash/ST-E3 with another in the hotshoe (pre-2012 bodies can remotely trigger the shutter, but a cable to the N3 socket is needed).

Hi Neuro,

Thanks for the response. I wasn't aware of the remote shutter triggering capabilities, that's something I will have to look into.

On the sync speed, I should have specified; I lose PocketWizard's proprietary HyperSync, which essentially allowed you to fire a full powered flash above your camera's rated sync speed. For me, I was able to get 1/400 on one of my bodies an 1/500 on the other, compared to the standard Canon sync speed of 1/250 or 1/200, which is a pretty big benefit to the PocketWizard system in my eyes. Because both systems can take advantage of Canon's High Speed Sync (Which I use regularly) I don't give a benefit to either solution there.

I just have to comment.  I swear I have NOT found the "perfect" system yet.  Each one comes so close ... and then misses it. 

I jumped on the RadioPopper bandwagon when they first came out. I used the PW TT5 system for several years. And about 6 months ago switched to the Canon 600s with with the ST-E3 remote.

My very most favorite thing about the PW was the AC3 Zone controller. With REAL/PHYSICAL switches and dials I could adjust settings without even looking at it. A bride could be walking down the aisle and I would have one set of lights flashing, then as she passed me I could switch to a different set of lights by quickly turning one switch off and another on. I barely had to take the camera away from my face long enough to flip the switches and then resume.

The downside to TT5 is the stupid RF interference with the Canon 580EXII flashes. I had 5 of those, all with socks on them and still had issues of flashes sometimes being too far to fire reliably (at just 20-30 feet!).

I love the reliability of the Canon 600s. I love that I have 5 groups to play with. I love that it works essentially the same way as the AC3 Zone Controller (being able to turn individual lights on or off, ettl or manual, etc).

What I _hate_ is that there are far too many button presses and dial turns to accomplish a single task.

Turn a light off:
AC3: flip a switch (often without even looking)
ST-E3: put remote down below me where I can see it (old eyes aren't helping), push a button, rotate dial to appropriate group, toggle off

Change the power setting is the same:
AC3: return a dial (often without even looking)
ST-E3: put remote down below me where I can see it, push a button, rotate dial to appropriate group, push a button, rotate dial to desired power level

Too many button presses and dial turns - all of which require that I watch the screen while I'm doing it because all of the buttons are "context sensitive" (meaning they change what they do based on what is on screen at the time). 

I would PAY EXTRA MONEY to get a remote that let me control my lights with physical buttons and dials like the AC3 Zone Controller.

Please pass the word along to Canon.

Try out the Yongnuo YN622C then. I have 5 transceivers and after putting complete faith in them for a number of jobs they've never let me down. I haven't tested beyond 30m but have mixed and matched the flashes between the 550Ex, 580EX, 580EXII and 600EX with no change. They have physical buttons, Hotshoe passthrough, AF assist beam, batteries last a lonng time, they are reliable, HSS is not problem, can be controlled entirely in camera if you want, etc etc. You could put the flashes down the aisle and press the group button by touch to change the channel as the bride moves. These things are absolutely fantastic. You can customise lots of functions too like remote flash zoom, mixing of ETTL and manual metering, PC Sync port built in and link lights blink on metering start. The RT system is amazing but very expensive and still limited more than the YN622C. I thoroughly recommended anyone doing remote ETTL to research and buys these....you won't look regret it!
