This was a quick edit but the tripod was on the road ,just to see if any softness could be down to movement due to the high wind
That’s pretty bad too. If that was my lens, I would not be happy. At all.
I think it's a bit early to draw conclusions about the lens. IMHO the shutter speed is way too low, the light levels are too low, and in this last photo there is significant light pollution from the side. If it was my lens, for the sake of my emotional health, I would go outside in a similar area in full sun during midday and shoot with the sun behind the lens first, manual focus on hyperfocal distance, on tripod, OIS off, f8, 1/500 or faster shutter, RAW, and edit in iridient or ADOBE with enhance details.
Personally, my IQ hit rate with landscapes is quite low. It is just not that easy to get everything in sharp focus, with no wind and in good light, and a lot of factors affect the image. I sure had worse results than these from a perfectly good 18-55 if I set up something wrong or the environment was not helping. Also fujis are not really easily landscape cameras.
