Hey, recently I've been playing around with Nikon AF modes but there are some that got me confused. At the lower front, there is 3 dials; Continuos, Single and Manual. My question is regarding the Continuous and Single Mode. To my understanding there is 3 modes; single AF, dynamic AF and the full box which I dont understand what it means. The problem is, when in Continuous Mode and Dynamic AF, when I focus lock the subject, as the subject move. The camera did follow but as soon as I press the shutter, the camera will snap the part where the AF point is placed. I don't really understand what is going on cause in 51AF with 3D Tracking, I can see the AF points follow the subject.
