You should have compared the Fuji 10-24 against the Canon 16-35L, that's the same focal length.
The Fuji 23 against the Canon 35.
I can post lots of photos between each on here and I challenge anyone to guess correctly which is which for every one. It is also natural that Canon high end glass cost more compare to Fuji, for one thing it is much more material being much larger, also it is also a faster glass. A Fuji 23/1.4 is not really technically speaking comparable to a Canon 35/1.4, that is more like Canon 35/2.0.
The bottomline is Fuji make some amazing glass, especially for the money. I am holding a 56/1.2 in my hand right now and it's a beautiful piece of glass, but at £850 you do pay for it, and to be fair, a Zeiss Batis 1.8 is the same price (less at the moment at £760) and arguably a better lens with IS built in. So pound for pound I would say Fuji glass are good, but not a bargain, it is in line for what you pay for.
