I have the good fortune of shooting terns, common and roseates and would like to know if their is a suggested custom function so i can achieve quicker focus. I seem to have trouble achieving initial focus against the sky, ocean and can also lag focus when they fly against the rocks before landing... Incredibly fast and sometimes aerobatic. Any thoughts would be appreciated. Also, I have my setting so the shutter will not fire unless i am in focus, good idea?
My gear is the 1DX and the 600II... Ill be back shooting them this weekend and would like to try your suggestions.
I have been using:
Tracking sensitivity -2
Accel/decel tracking +2
AF pt auto switching +2

Also 9 pt expanded...
Thanks,
Ann
Also, suggested ss above 2500 for terns, correct...
