Hi guys, my recent camera gear is 7d mk2 with canon 100-400 mk2, now I’ve heard from a few places that this setup with a 1.4x extender will autofocus at F8. Is it just the mk3 1.4x extender that will do this & which focus points are active when used & what’s the quality like?. Apologies if this question as been asked, which I’m sure it has.
Regards
Sean
