I'm having trouble locking focus for birds in flight. Using my 7D mark ii and my 100-400. Set it to BBF and servo.
I tried everything from a small zone, to the middle 1/3 zone, to the entire full zone. Oftentimes for birds in flight the AF is jumping around everywhere!
What settings do you usually use? Does it vary depending if it's flighting towards you, away from you, side to side, etc...? Do you all switch "cases" often?
Thanks for your advice in advance!
