The X-T2 gives a bit more control over video autofocus, with the main change being that you can choose between the existing 'Multi' mode (where the camera chooses what to focus on), and 'Single,' where you specify the focus target. This target can be moved as you record and the camera will refocus on your newly-chosen subject. AF-L is also available, to stop the camera refocusing when you don't want it to. This honors the toggle/hold setting specified for stills shooting mode but there’s no on-screen indication of when it’s active and you can't move the AF point while it's applied, so it's not nearly as useful as it could be.
