With that in mind, I would be curious if this presents in af-c as well. Try both holding focus on (with a3 off) while panning around as well as quickly engaging/disengaging it as you are doing now. Another thought, could the back button be intermittent? Was there any problem with half press shutter button focus? You could test the back button in the dark in af-s by watching to see if the af assist lamp responds quickly to your presses. Or you could eliminate the back button entirely by programing your fn button to af-on.That's all I got.</blockquote>
