I am going to try back button focusing with my D7200 and understand their are 2 steps to do this under "Custom Setting Menu":

(1) f Controls - f4 - AF-ON

(2) a Autofocus - a4 AF activation - AF-ON only

Before shooting using BBF I mostly used AF-C and switched between the Release & Focus options. Does it matter if a1 AF-C priority selection is in Release or Focus when using BBF.

Yes, those are the correct settings.

AF-A will only fire the shutter if the AF system deems the subject in focus which it may not always do even though the subject is in focus. For example you are panning along with a bird and you momentarily drop off the bird with the AF sensor, the camera will stop shooting until it decides it has reacquired focus even though the subject might still be perfectly in focus. Go with Release for that setting.

Hi Paul,

I believe that once you have tried BBAF, you will never return to traditional auto focus. It becomes second nature quickly, and far superior IMO.

Steve Perry has a very good video on the topic that is Nikon based.

Have fun.
