Note on BIF Auto Focus for the D5
One of the AF modes on the D5 that I found useful for BIF ( for these parakeets in flight) is the “Group Area” AF mode setting. Here the camera tries to focus on the nearest point withequal priority to all five AF points in the group. And when you pan, the AF is maintained. Since most of my parakeet shots were of the birds flying below me, the nearest point AF was the one to use and is working well. In case you want to be super accurate and in very challenging situation say low contrast, Id choose 9 point dynamic AF and keep the AF on the subject all throughout.
The not so regular shots
This looks like a “Pterosaur” landing 🙂
