 Adey - "Back-button" focusing with C-AF  is possible now.  I set focusing on the upper of the 2 function buttons between the grip and the lens and press it with my 3rd finger.  One press for single AF and re-compose as per conventional back-button or press and hold keeping your focus point tracking the subject for C-AF
