Canon 600EX RT Help!

I have 2 new Canon 600EX RT speedlights & am finding them difficult for me to learn compared to my sweet little 580EX IIs. Here's some things I am trying to find the answers to in the manual (I think my biggest problem is I know what I want to do I just don't know what it's called in the manual - that & I'm apparently quite dim):

Can I use my Yongnuo 622C triggers with these?

Can I have both the 600EX RTs off camera & trigger somehow (assuming the Yongnuo's won't work)?

When I adjust setting in camera for the speed lights, I can't seem to get the zoom setting on the slave unit to change?

Thanks for any assistance! Oh & while I"m at it - I've been missing responses to posts becasue for some reason I stopped receiving email notifications - where do I change that back?

Thanks so much!

Heya,

So the 600 RT's system is different from the YN622 system. The communication will not be complete. You can use the Yn622's with the 600EXRT's, but it will not allow you to remotely control the menu through the camera that way. The 600EXRT system was designed a different way, and is not meant to use things like the Yn622. If you use the Yn622's, you'll basically be using them as manual flashes essentially. The 600 RT system works with itself, so it's ideal with other 600 RT's, or anything ST-E3.

I'm curious, why did you get the 600EX RT's in the first place? I assume you didn't get them for the protocol they use to work (off camera, menu system, etc) just based on this thread.

You can have both 600EX RT's off camera and trigger them, again, see the ST-E3 system that was made for the 600 system.

Or, you can get Yongnuo's system for the 600 system (much cheaper, works with Canon's 600 system; note this is NOT the same at all as the Yn622's). The YN622 & YN560 is not an integrated system with the 600 system. They're totally different.

Very best,

FYEO (for your eyes only link), How to's / FAQ, then the bottom of that page.

You may want to take a look at the YN-E3-RT (or ST-E3-RT). I have the Yongnuo version and rely on it professionally.

It will allow full control of your 600's from your camera. And, it will allow you to stay out of the camera's menu system. In my opinion, that's a big thing. Having buttons and dials to control functions is more user friendly and intuitive.

The Yongnuo's only downfall is a tendency for the adjustment dial to skip every once in a while. What I mean is that you may have to turn it four clicks to make three clicks worth of adjustment. I've never had it miss two clicks in a row. A plus is the AF assist light that it has. The Canon does not have AF assist. Some folks don't like the AF assist pattern, or alignment, but I've never had an issue with it and can count on it to lock focus in light so low I can't see my subject clearly (using 5D mkIII's).

The features on the YN/ST-E3-RT are the same as when you use a 600 as a master on your camera to control and off-camera 600 slave.

Yes. But you will need 622 triggers on both of them, and a 622 transmitter on the camera hot shoe. The 622 system does not communicate with the same protocol as the 600ex-rt built-in transceivers (usually referred to as the Canon RT system).

Yes, with an addition piece of gear on the camera hot shoe you can have both 600ex-rt fire wirelessly using the Canon RT system. You need one of the following:

- Canon ST-E3-RT controller ($289)
- Canon 430exIII-rt ($299)
- Yongnuo YN-E3-RT controller ($80 ST-E3-RT clone)
- Phottix Laso Transmitter for Canon ($160 ST-E3-RT clone)
- A third 600ex-rt
- Yongnuo YN600ex-rt.

Both ST-E3-RT clones offer AF assist beams, which the original Canon product does not.

Using the Canon RT system means fewer possible failure points, fewer things to turn on and off, and fewer AA batteries. It's more elegant than adding external 622 transceivers to speedlites that already have built-in wireless transceivers, and you can get it all working for as little as the $80 to get the YN-E3-RT.

CORRECTION FROM accord: It appears the the 622 system can send zoom focal length values to compatible speedlites if you have the YN-622C-TX transmitter. The Canon RT does not support this.

If you follow the thread

You will know that 622 system can control zoom range remotely.

With the yn/st-e3-rt you can not control the zoom of slave units

I've never had the need to change the zoom of a Slave flash when I am shooting. I take care of that when I am setting up the flashes. If you use the modeling light feature of the flash to align and zoom the flash to give the coverage needed there is very seldom a need to change that when you are shooting. If you're using a modifier with the flash then get to know what zoom setting works best with that modifier, then "set it and for get it" as Ron Popeil used to say.

It seems kind of ridiculous to me to buy a 600EX-RT, let alone a pair of them, and not utilize the built in radio system and use one of the best wireless system's available. The Canon Wireless RT system is the radio system you look to see how you can integrate other flashes into rather than how you can integrate the 600EX-RT into another system. I would be looking at more 600EX-RT's, an ST-E3-RT (YN-E3-RT if you have an older DSLR so that you can use the <Gr> wireless mode) and if I had other non RT TTL Canon or Canon compatible flashes, I would be looking to integrate them into the Wireless RT system with either YNE3-RX or Laso RT receivers.

This is true, and while being able to do this would be an extra level of flexibility, when I actually thought about it, two things came to mind:

1. A Canon 600ex-rt only respects the focal length information it gets from the hot shoe in auto zoom mode if the head is locked in the default forward position. As soon as you tilt it, it only responds to setting the zoom FL manually. If this is how they behave on a 622 hot shoe as well, it would make this feature less useful to me as I usually tilt and rotate the heads of speedlites when they are used off camera. Maybe someone could test this and see how it works with the 622c?

2. Zoom FL of the flash head is designed for when you're using the speedlite on camera, with a zoom lens. When I have speedlites off camera, I rarely have the need to adjust the zoom on the fly; I already know what FL setting works optimally in each of my speedlite modifiers (softbox, Rogue grid, etc.), and I set the FL one time when I put the speedlite into the modifier. I almost never use a bare speedlite.

Completely agree it would be odd to use a 622 system on the canon rt system flashes instead of using the rt system it self. I myself have never had a need to change the flash zoom while shooting either. Was just stating that because I'm the OP it stated that they couldn't change the zoom remotely and seemed to be something they are wanting to do.
