I spent some time trying for some flight shots using the animal eye detection auto focus on my new 45Mp toy - the much sought after Canon EOS R5, which I pre-ordered the day after its launch in June. Even then it didn't arrive until mid September.
This much vaunted AF option struggled to find the eyes but these wheeling Red Kites were pretty challenging subjects. Hopefully it will be more successful on better behaved subjects - a forthcoming session in a photo hide should be a good try out.
