Iso set to auto and camera adjust it to 400 with flash unit On

Juliuslepetit — Sat, 23 Mar 2013 16:42:21 GMT

What about that ?! In Av, Tv and Manual modes, when the flash is turned on, that my ISO settings are on AUTO, when I pressed half shutter, the camera set the ISO back to 400!

Now I have to fix my iso manually to 800, 1600 or else to be able to catch some ambient light!!

Why !!? I want it to be auto, not 400 ! I request a fix to this issue or a On/Off at least !

I really don't understand why Canon is doing this.

Absurd.

Interesting. I just shoot in Manual when trying to do something way off-exposure with flash. I have never noticed the ISO resetting itself though. What camera are you using?

Yes, noticed this in the past on my 7D but I really don't use auto ISO with flash so it hasn't been any issue for me. I. Actually forgot about this condition until I read your post.

Edit: And if I recall right, the Auto is always and only 400, is that what you are seeing?

I am actually using the Canon 6D.

I'll train myself to fix the iso setting instead.... but I would like to have had the choice to do what I want with these settings.. !!

I would like to let the iso auto to max 3200 iso and with a 1/180 to 1/60 option turned on in Av mode and when theres not enough light, the flash take the lead, on ettl...

thanks
