When you use Live View, does it close the shutter to focus?   <— One Shot, when you half press the shutter.

In Live View, doesn't it, almost by definition, use the sensor to focus? IOW, it couldn't be focusing with the shutter closed?

Canon DSLRs can do either.  I think turning off ExpSim is what causes it to switch modes, from image sensor focusing to AF sensor focusing.

 Okay.  I just tested this on my 6D.  

 

In the Live View menu screen, one of the last red ones, you can set the “AF Method”.  When it is set to “Quick Mode”, then focusing is achieved by dropping the mirror, and using the AF system, and then raising the mirror once focus is locked on a subject.  It is much faster than image sensor focusing, which I guess explains the name.

naipes indicates that using single point AF with center FP gives poor results (i.e. agreement between viewfinder and LiveView, but using one FP up gives good results.

 

Can anyone explain that other that being due to a camera issue?

I cannot.  But, the problem seems to happen with only the 50mm f/1.8 lens.   [???].

 

I was going to suggest switching focusing modes in Live View, as I describe just above, to “Quick Mode” and comparing results, assuming the camera body has it.

The OP didn't state that, a second poster stated that. The second poster was using a 2D poster for his comparison shots. Even the slightest error in either the lens or the camera (even within tolerance) will show up on a 2D target. That's why Canon recommends doing AF microadjustment where you have foreground and background so you can see where the camera is focusing.

Also see my post above with the addendum from Roger at Lens Rentals.

Good clarification. I meant the OP of this particular problemproblem (Naipes) that is being discussed now.

With my 50mm 1.4 lens, ill have the same results when using the viewfinder or in live view. Still out of focus when under f2.8

Thats my only prime lens. So i dont have anything to compare it too. My kit lens only goes to f3.5
