There has been some discussion about this in the past but I can't find a solution for my situation. My focus area jumps around when I auto-focus the camera. I want it to stay in the centre and only move when I move it with the joy stick. I know that it can move if I accidentally hit the joy stick but this is not my issue. While I am focussing, I can see the focus area jumping around to focus on different areas. How do I prevent it from doing this? thanks Len
