At a high level comparison, the Fuji should be a much better lens optically and physically, thus could justify its price on that. The Canon as far as I can tell doesn't use any exotic glass compared to 3 ED elements in the Fuji. At a practical level the Canon has severe LoCA, so if the Fuji can approach APO like performance that would be a big plus. With the usual cautions of comparing MTF charts across systems, the Canon at 30 lines/mm is lower than the Fuji at 45 lines/mm! Ok, the Canon is a notch faster but that is also slightly offset from the focal length difference. Plus Fuji got the S and M lines to track each other closely, and has weather/dust sealing. If the Canon were an "L" lens, maybe the comparison would be closer.
