Bonjour
avec mon émetteur Profoto , mes eos R se mettent en Iso Auto alors que j'étais en manuel. En configuration normale comme en haute vitesse.
une expérience similaire?
merci

I occasionally run into a similar problem on my two EOS Rs. I always shoot in Fv and vary only the aperture, but sometimes everything (shutter speed, aperture, and ISO) gets set to AUTO.

I don 't know why this happens. I mainly suspect user error (I am cursed with ten thumbs [since your native language is French, I probably should explain that this is an idiomatic expression for being quite clumsy]), but it may be a firmware problem.

I had once first the problem with a GODOX controller, then GODOX made a firmware update saying they corrected exactly that problem, , the problem disappeared and now is coming back . I think there is a electric problem in the eos R. I update yesterday the firmware to 1.8 ( and they said for the 1.6 4. Corrects a phenomenon in which high-speed synchronization with use of an external flash may not operate properly depending on the camera’s setting for C.Fn2 "Set shutter speed range") .
So there is well a eos R problem with iso Auto
