I love to photograph birds and have done so with a D3100 using AF-C mode. Now I have a new D7100, would you use the single, 9 or 21 sensor setting with the AF-C mode??? Also, when if ever would you use the 3D mode. I have just used it playing around. Is there a real life application or just use the AF-C mode as discussed for birds above.
I shoot a d7100...I am not sure I can explain 3D but I'll try.
Hypothetically, let say you have you camera set on 11 focus points and AF-C. What you see in the viewfinder is a single STANTONARY square but there are 11 focus points around it. If the subject stays within that "cluster" you are good. If it moves out of that cluster you are not good.
What 3D does is move the ENTIRE cluster around...from right to left, top to bottom...moving the single square along with the 11 focus points.
I think...lol

Ken Rockwell gives a good description of the D7000 3D autofocus mode:
"3D allows the D7000 to choose any sensor it likes as a subject moves all over.
Once you select 3d, select a sensor with the rear multi-control switch, and as soon as the D7000 gets something in focus, the D7000 will track that sucker all over the frame.
The D7000 is the smartest camera on earth for doing this, at least as I write this in January 2011. Once it gets focused, the D7000 uses distance, motion and even color information to track your subject all over the frame, and keep the correct sensor selected and the focus locked to it like the bite of an angry pit bull. Once you select a sensor and the the D7000 grabs focus, it's not letting go until you've got your shot.
I use this mode if the AUTO mode won't pick the correct sensor for me. I use this even for still subjects because it allows me to recompose and watch the D7000 keep my actual subject in the AF system's crosshairs, saving me from having to move more buttons."

I use AF-S for birds but probably should experiment more with AF-C.
But more importantly I have the camera set to not fire unless focus is achieved (focus priority release). I ale set continuous shooting and pan through a bird in flight. The camera fires when it achieves focus.
I sometimes get part birds but they are always in focus.
