I was using Auto Area AF with some blocked out distance spots along with animal detection. Bird detection is not supported in AC yet. Hope it will get added.What was the fix for the AC problem?
I had used this with my 100-400 successfully on 4.0 when there was no Bird detection, but was struggling with it on this fountain.
This morning I switched to C1 with a 19x7 rectangle along the top of the fountain. Took 2655 shots and most were in focus. Only Auto Area AF supports blocking out focus spots so I could not do that but it didn't matter.
Bird detection is good in a situations like this I hope it gets added to the FW.
