Nikon Rumors posted this video which explains using the AF On button on the back of the camera rather than holding down the shutter halfway then recomposing. The camera needs to be put into AF-C (continuous) for this to work. Plus the shutter release button has to be set so it no longer controls the AF.
Supposedly if the AF On button is pressed, the camera will lock its focus and won't change. You can take shot after shot without having to refocus. And if the subject moves, you can hold down the AF On button and it is supposed to track the subject.
Has anyone tried out this camera setting?
