It's probably best not to use Mico sd cards. The adapter is an extra part that can fail/cause problems. I know they cost a bit more, but full size SD cards, in general, work better, are more reliable, and give better read/write speeds. Again, don't get cheap cards - the X-H1 has two uhs ii compatible card slots. Use good uhs ii cards (v60 is fine) and you wont regret it.

I have my custom slot one set to a default profile so I can just select that to return to default.

I don't think there is a firmware update for the 10-24 r ois wr, only the older 10-24 r ois, which, obviously, wont install and isn't needed with the newer lens.
