I continued to play around with menu settings. If use the settings below, the AF-L button will work like it did in the XT-1. However, you lose back button focusing with the AF-L button. I the Button/Dial Settings: Shutter AF On; AE-AF-Lock Mode. AE & AF On Off Switch; In the AF/MF Section: Release/Focus Priority: Focus.
When I set Button Dial Settings> Fn/AE-L/AF-L>Fn-2 to AF On, I am able to use it as a front button function in place of back button focus.
