5D3 Live View focusing question.
I'm trying to get my new 5D3 to behave like my old 5D2 when focusing in Live View Mode.
On both cameras, I set the "AF mode" to "Live mode". I go to Live View and position the focus box where I want it.
On the 5D2, I press the "AF-ON" button to focus (and wait patiently). Then I use the shutter botton to fire. Pressing the shutter button half way does NOT attempt to re-focus. It just immediately fires the shot.
On the 5D3, the "AF-ON" button does the focus OK, but so does the shutter button. After setting the focus with "AF-ON" I can't fire a shot without waiting for a re-focus.
Am I missing something? Any way to get the 5D3 to focus with "AF-ON" only and not the shutter button?
