Canon 5D mark IV + 35mm Sigma ART f/1.4 live view issue

[Patlezinc]

Hi everyone.

I just bought a 5d IV and I have an issue with my 35mm.

I have calibrated the focus lens with the usb dock. That is ok.

But I have a problem in live view.
When I do the focus in live view, if i focus with a non-centered zone, for far objects (More than 1 meter), focus is blur.

I have disabled all corrections.

I thought it was impossible to miss a focus with live view...

Two more infos :

- my Canon 24-70 F4 at 35mm is working perfectly with the 5D
- the 35mm is working perfectly with the live view on the Canon 6D.

So the lens is ok i think, but not with the 5D.

The question is : can someone try to focus a far object with the live view on his 5D4, on the right or on the left with a 35mm ART?

Thanks.

Here an exemple :

Auto focus (impossible to do the focus) :

Manual focus:
