Hi ,
Focus Bracketing is one of the coolest features found on the Fujifilm cameras. It's also one of the most confusing. You can use the built-in Focus Bracketing setting, which is found on all of the newer Fujis, as well as the X-T2 and X-H1, to create some really stunning and unique photographs, where you shoot a series of photos and combine them to achieve a wider depth of field than you would normally be able to get.
Traditionally, focus stacking techniques are often used in closeup and macro photography, but there's no reason you can't use it in other types of landscape and travel photography. In fact, I think it would be a really fun challenge to try using this technique to capture different subjects in an interesting way.
