If you like to spend your time on focusing it is not difficult for sure. Even not old, but just manual focusing with EVF is not something I'm finding simple.
Autofocus is very often focused on wrong things. Or you are in wrong focus mode or the spot focus is at wrong place (so you have to remove camera from your face and start to fiddle which slows down). I've assigned the AF / AE lock buttons to other functions too on my X-T30.
Manual focusing with the edge focus assistant is pretty fast way in my opinion and I am then focused at chosen place. Also I like to play around with the focus area when composing, sometimes focus can be used as a composition tool too. One day I was street shooting with digital and I used prefocusing with something like 1.5m-infinity hyperfocal area. No need to focus there, just fast reactions for shutter. Pretty liberating to use small apertures and still get 1/250 or 1/500 shutter times!
For family photos I prefer of course the fast autofocus Fujinon lens because getting a good photograph of the little ones is absolutely a ninja skill without all the help from the camera
