Sharing some of my AF testing on Fujifilm X-T4 with various lens combination
Test 1
Fujifilm X-T4
Canon EF500mm F4 IS2
Fringer EF-FX II
Setting
ISO 1250, 1/3800, F5.6 AF-C, Zone AF (2nd largest area)
#
the bird (tern) has enough contrast again this kind of background.
Overall, it lock focus on the bird fast and track well too as long as we able to follow the flying path and no big change of background condition
*** the AF Range limiter will help faster and better tracking
*** smaller AF zone also help faster and better tracking
