To be frank: the X100s and X20 sample shots at Fuji’s website are not that good. I agree with MJR, who said in the comments: “I’m sorry Fuji but these are the worst samples ever. (at photographers fault) I’m heading back to http://fujifilm-x.com/photographers/en/ to feel better.”
So, take a look at the dedicated X-Photographers pages (with X100s and X20 samples) here. Just look worldwide for them!
