searching for a compact and wide angle lens

Hi everyone,

like the title says I am looking for good wide angle lens (like 10mm-18mm), that is compact and lightweight. It doesnt have to be from Fuji, could also be from a third party producer. I just want to go more often outside and not have to carry a 0,5kg objective with me. I tried to watch reviews on some objectives but was a little bit overwhelmed. A nice AF would also be pleasant. So what do you shoot with and why? Thank you already for the help.
