6D and Yongnuo: Anyone used YN-568EX and/or YN 622c triggers on a 6D yet?

Curious.  Was thinking of getting one, and maybe the YN 622C.  Specific comments on the exact matchup, or even comments on any of the specific pieces.  Thanks!

When I first tried them, there was a little hiccup. The photos were underexposed by a stop or two on ettl. Then I turned them off and tried again. Everything worked fine. Had no problems since.

I recently got them. Used them once for a product shoot which I used  a 430exII. I can control through the camera with ease: zoom the flash, exposure compensation, set to manual mode, change power output. Works fine, so far.

My yongnuo st-e2 didn't work with the 6d. Same problem with 5dIII which it would have sync problems. That is why I got the 622c.

Now I'm debating if I should just go 600rt down the road. Damn flash!

Good luck!

Almost every time a new camera is introduced, third party flashes have some issues.  The manufacturers update them if its a current product, but if its a old model, forget it.
Its kinda like your issue with the 6D and LR3, no updated for old products.
I'd get a Canon flash, they will likely work with new Canon models for many years.

Update on 622c with 6D:

I found that one transceiver gives me different exposures than the other when on Camera. Also when the flash goes to sleep the one transceiver can wake it up. The other transceiver does not does not.

So I am in the process of returning them since one transceiver doesn't work correctly. Could be a bad one, but I need something solid?

I'm going to go with what Mt Spokane said. I should have done that the first place and get a canon one. But I was being cheap.

This happened during a shoot when I found these odd problems. Lucky they were not in a hurry.

It is likely that there is no problem with the 622s.

When you place a transceiver on a camera, the transceiver's settings are applied to the camera's flash control menus. If one has an FEC of zero and the other has FEC -1, the camera will behave differently, according to the unit mounted. There are other settings that do that. It can be worth using one as a dedicated transmitter to avoid this hidden change.

PS I have tested the 6D with the 622s, and they performed flawlessly in all features except one. I couldn't find the DOF button to test the modelling light before the 6D was wrenched from my grasp.

I've got the 622C's and 580EXII and 430EXII and they work flawlessly.  Modelling also works well.  I did a "hair toss" shoot (don't have permission to share these images) in near dark conditions and the modelling allowed me to focus accurately and fairly quickly every time (obviously I did pre-focus for this kind of thing).

I just got a 568EX from Amazon today.  It turns on and fires with the camera in manual mode, but I've tried it on a 5D II and a 60D and can't get the cameras to recognize it.  Both cameras show no external flash warnings when I try to get to the settings menu.

Anyone else have the same problem?
