when to use 51 point 3D tracking ?
I am an amateur photographer trying to improve my photography skills.
Over the weekend I was shooting (for the first time shooting any sports) an ice hockey game and then some kids doing tobagganing. Now I wonder whether I should have used 51 point 3d tracking feature of my D700 camera (with 70-300 lens). I just used 21 points (with centre point active). But my AF points choice limited me to always keep the subject in the centre of the frame (which sometimes cropped some of the 'best composed' shots) I was always trying to bring my active AF point on the moving subject.
I will soon post some shots from tobagganning and ice hockey soon..
Any other tips while shooting such sports will help too..
Thanks for your help in advance,

Use all 51 points when your subject is moving erratically around the frame and you can not track it using 9 or 21 pt AF.
You don't have to use the only center AF point when using Dynamic Area AF! You can use Dynamic Area AF and move the Active point(s) around the viewfinder via the multi-selector.
Good Luck and Enjoy your Nikons!

I know I can use the multi-selector but when you are shooting sports I don't have any time to move my Active AF points .. rite ?
I think I do need to use 51 point 3d tracking in sports shooting assuming it does correct/intelligent selection for me on runtime to select the correct subject in this case, I have a feeling (and some experience during non-sports shooting) that this 51 point 3d tracking is not very accurate or correct in selecting the correct point of the subject.
For example, when I have framed more than 2 players in my frame, I want to shoot the player that's slightly behind (in the frame) the 1st player, how can any automatic (including 51 pt 3d tracking for this camera) determine which player am I trying to shoot in this case, I dont want to be in a situation where I am relying on the camera to select somebody and it selects someone else to be in focus.. the only option in that case for me will be to shoot at larger f stop to bring both of them in focus - which is okay in some cases but not when you trying to isolate a specific player.
I hope I have explained my dilemma a little better this time, what do you think ? Or should I just give it a try to see what 51 pt 3d tracking does (which i will in either case) - i was just hoping to get some expert opinion from some sports shooters (based on their experience) before I try it ..
