[QUOTE="Foo Fighters, post: 343171, member: 29609"] Hey guys, I'm trying to get the best from AF system of the D810, and I'm having difficulty understanding the use and application of Group Area AF. Is it for moving subjects with predictable movements toward and away from the lens? When acquiring focus of a moving subject, am I supposed to try to keep the moving subject within the center of the Group AF crosshair, while attempting to move the crosshair with the thumb dial to the predicted path for which they are moving? Or am I supposed to sort of pan the camera hand held, and try to maintain the subject in crosshair that way. Or am I supposed to be stationary, waiting for the subject to move into the crosshair? I'm probably way off base either way. I'd like to use my 3 year old son running around a table as an example. I'm standing approximately 15 ft way, and would like to get his face in focus in all the shots as moves around the table. If I'm trying to get his face in focus, am I using the center box of the crosshair on his face, while the surrounding points attempt to acquire focus if my user point fails? Also, when using Group Area AF in AF-C mode, do you keep it in Release + Focus for best results? I'm sorry for all the stupid questions, but I can't find a thorough explanation anywhere - mostly testimonials on how great it is. [/QUOTE]
