Hi everyone
Having an issue with my 600ex-rt. When using my Yongnou's to use the flash off camera, it will not allow me to keep it in manual mode. I switch the flash to M, and when I focus on the camera the flash automatically goes to ETTL. Anyone have any idea what could be causing this?? I have tried all my other speedlites and they stay in M, just not the 600ex-rt
But, yeah, as I remember correctly, it doesn't matter, what mode you have on - just press the buttons until it syncs with transmitter and after that use transmitter to change power on the flashes.
