YONGNUO 600 RT II flash / RT transmitter issue

Hi,

 

im having an issue with a new  YONGNUO 600 RT II flash and YN-E3-RT II Transmitter. I have then paired together properly but there is 1 function that's not working correctly. When I work in ETTL and set a flash exposure comp in the transmitter, it's not carrying over to the flash or camera. When I have the flash in Manual mode, the adjustments are properly moving from the transmitter to the flash so I know they are paired together properly? How do I fixed the ETTL issue?

This can only be solved by Yongnuo. Canon doesn't have info on 3rd Party products or how they'll work with your camera. Its up to the 3rd Party manufacturer on making their products work on Canon cameras. Its not Canon's responsibility to make 3rd Party items work on their camera.

This is also how the Canon ST-E3-RT and Speedlite 600EX II-RT works. If you dial in some exposure compensation on the transmitter it is not shown on the receiver / slave Speedlite. This is because the transmitter is doing the compensation and it might be connected to multiple Speedlites.

Did you try setting exposure compensation on the transmitter to -3 and take a photo then set to 0 and take a photo the flash exposure will change in the pictures.

Canon's EOS system allows flash compensation to be set in multiple places.

  • On the camera
  • On the Speedlite/transmitter on the hotshoe (or via the camera menu for the Speedlite/Transmitter)
  • On a receiver / slave unit off-camera

My EOS 7D Mark II has a button on the camera to allow flash exposure compensation to be set on the body, same for many other DSLR. If no compensation is set on the Speedlite or transmitter on the hotshoe, the camera set value prevails. If a Speedlite or transmitter on the hotshoe has compensation set on there it overrides the camera set value.

Mirrorless cameras - just checked EOS R6 / R10 / R6 Mark II, when you set flash exposure compensation via the camera menu of a connected transmitter or Speedlite the change is also shown on the device, but the camera uses the old camera settings icon on the INFO display. If you then change the compensation on the Speedlite or transmitter it takes priority and overrides the camera set value, and the camera info display is different too.

My approach to this is the same as it has been since before mirrorless. I set flash compensation on the transmitter or Speedlite on the hotshoe always. It is more logical to my brain to change the compensation there, and that is the one that has the priority.

This is the info screen from the EOS 7D Mark II, which has a button to change flash compensation on the camera.

Then this is the EOS R6 Mark II

Wow..appreciate all the info. 

I thought I was losing my mind.

Just don't get why they are smart enough to show the manual setting adjustments from 1 to the other but not the ettl adjustments 

Possibly because it is also possible to adjust the compensation on the off-camera Speedlite in addition to the one on the camera.

Say I have two off-camera Speedlite 600EX, then I want one of them to be 1-stop less than the other. I set one unit to -1 on the Speedlite, but leave the transmitter on the camera at 0.

This is less useful in the radio system with group mode and five groups, but in the earlier days of the Speedlite system when only three groups could be controlled this was a useful trick to know.
