Hi,sorry I forgot to answer....I too also shoot in Av or M but on one of my last photogs meeting I found a Canon user who played a bit with my camera and now I can focus on backbutton
Hi, I followed your steps, even before I read this, but it still doesn't work. It works on my 5D, it worked on my 60D but not on my 6D. Is there any other setting that could prevent this from working? Kind regards Sabine Schnell
