I have a Canon 1DX with the new 2.03 firmware and I have notice when using the Auto ISO it works great, but when I attached my flash the auto ISO is not working correctly, I am using an Canon 580 EXII flash I have try using in Manual mode and ETTL but either mode the auto ISO will not work correctly?
Is there something in the setting that I must enable to disable?
When you use flash with auto ISO, ISO will go the 400 and no higher. If you don't use flash with auto ISO, the ISO is unlimited. I think that may be what you are getting at, right? If that's the case, then it's normal that the camera will not go higher the ISO 400 when using a flash with auto ISO.
Ooops. I see a couple folks already stated this. I did not read further than the original post and just answered it.
