Ah that is where we differ in operating principle (maybe).
I put the D500 on Dynamic Area AF-C 153 points, and then it will capture lock as bird(s) enter the viewfinder and the AF lock is achieved before it is in the central section. I cant do the same on the D850 which only has Dynamic Area in the central section.
I have just been looking at the D850 manual. They have a section called Subject Tracking AF (see page 43). This seems to provide similar functionality to the D500 as it says "Position the focus point over your subject and press the center of the multi selector. The focus point will track the selected subject as it moves through the frame. To end press center of the multi selector again."
I find that this works well for me.
How does the dynamic area mode choose to focus on the bird flying at the edge of the frame if there is a tree or other object in the middle of the frame?
I will have a look at the Subject Tracking option on Friday.....got visitors tomorrow.
