I am not so used to shooting in AF mode, I neither am fond of it. Nevertheless I see it has advantages in some conditions. The thing I hate about it is that my EM5 is choosing a part of the frame to focus there. A green box appears somewhere in my frame and I have no control over it whatsoever. I programmed the Fn-1 button for 'AF Area select'. Every time I push Fn-1 and put the 9 boxer square in the centre of the frame, where I want to to be. What should I do to make it stay there?
