Hi !
I recently migrated from a canon to a fuji x-t2 for my sport photography. I had to find out how to focus sometimes on the left of the frame, and then a split second later to focus on the right of the frame... And... it's easy !
I describe how I do it on this post :

If you have additional ideas, suggestions, please leave a comment…Thanks !
