Quick Focus and Liveview

[eco_bach1]

Hi
Perhaps this is not a ML specific issue but on my 7D, if I leave AF enabled on any AF lens I have, and set LiveView focus to 'quick mode' with live view enabled., I can quickly get an accurate focus before shooting video by half pressing the shutter

Great trick in run and gun situations and your talent is constantly moving.

No matter what I try I cannot get this to work on my 5DMark2.

Ok, also obvious, the af-on button on the back of the camera...but how do your reassign this button to a half press shutter?
