[6D] exposure différence between LiveView (well exposed) and Viewfinder (underexposed -+3Ev)

[pouloutos]

Hello everyone,

I have a problem with my 6d. When i am in extremely low light, I have +-3EV between liveview and Viewfinder.

I took pictures with LiveView and viewfinder, and the pictures with viewfinder are underexposed about +-3Ev (with or without the eyepiece), but only in low light conditions. In normal light conditions, the two metering modes are exactly the same. I rebooted with factory settings but the problem still to solve.

For example in AV or P mode, the 6D can show the following settings with the same parameters :

- 0.3 second with Viewfinder => Underexposed +- 3EV

- 1 second with liveview => Well Exposed

Other exemple, with lenscap, 100 isos, f4 :
- Viewfinder 15 seconds
- Liveview 30 seconds + (flashes)

Is there anyone have the same problem or have an idea ?

I Made a litlle Video to explain my Problem :

We didn't see finals pictures in the vidéo but, the picture with viewfinder is underexposed about 2-3 Ev.

Thanks for your reply

Ok, i will call my technical support, or not. If all users experiencing this "problem" i don't think a roll back at canon customer service can fix it.

Once again thank you all for your help.
