I recently acquired a vintage Canon EOS 7D Mark II with a low shutter count. Initially, I had very good results for birds in flight, but later I started experimenting with the very sophisticated autofocus settings with less than adequate results. I would of course shoot in AI FOCUS and AI SERVO.
What are the community's most successful autofocus settings for birds in flight using the EOS 7D Mark II, which has a much more sophisticated AF system with 65 cross-type AF points than earlier AF systems such as the 19 AF point system of the 7D?
