First post by me, but I've been shooting X-Pros for five years now.
I love the results I get on a good shallow-DOF portrait with my 56mm 1.2, but when it's wide open or nearly,
1) I miss accurate focus on eyes too often
2) in iffy light, autofocus is slow.
I've tried zone focus, single-point focus, AFS and AFC, and Face Detection. I have yet to settle on a magic combination of settings where (e.g.) I reliably nail focus on the eyes of my bored or antsy kids.
What do others find the most reliable and fastest way to focus on eyes with this lens?
