My impression from the Fuji is more "yeah, you can now have a superfat UWA lens for Fuji, but it's neither saving weight nor size nor money". Plus other disadvantages like the usual filterholder problems and focus by wire. Other than that, it's a WR type, so should take some rain - nothing I can say about a lot of my wide angles (the 16/1.4 being one exception)
Because neither is that wide (and not that fast, but that is secondary). That is why not
